DESCRIPTION
Fd
is a file & directory maintenance tool
considered for the text terminals on general UNIX.
It aims for a clone of the same named utility
which is made for the PC/AT compatible machine and PC-9800 series.
In fact, it is upper compatible functionally.
Fd
shows the browser screen listing files when you have invoked it.
You can input some key which is bound each command,
to execute various operations.
(In the following description,
(UNIX)
means that the operation is implemented only on UNIX version
and not effective on MS-DOS version.
As well as it,
(DOS)
means that the operation is implemented only on MS-DOS version.)
Options
The command line option is used for setting internal shell operations
and setting the internal variables described below.
You can use any variable name as the internal variable,
but
fd
can accept only those
which are described in the below section of
ENVIRONMENT VARIABLES.
If you specify
directory,
the current directory is moved to the directory initially.
If you specify
directory2 ...,
the split window mode is invoked,
and the current directories of the supplemental windows are moved to the each directory.
The following options are available for the internal shell.
- -c string
-
Commands described by
string
are executed and exit immediately.
It is effective only when it is invoked as
fdsh.
- -i
-
If the
-i
flag is present or if the standard input/output is a terminal,
the shell is the interactive shell.
- -s
-
If the
-s
flag is present or if no
args
is specified,
commands for the shell are read from the standard input.
Any remaining argument specifies the positional parameter.
- -r
-
The shell is a restricted shell.
Specifically, the following operations are disallowed.
-
changing the current directory
setting the value of
$PATH,
$SHELL
and
$ENV
specifying command names include
/
redirecting output
(>
and
>>)
IN_DIR OUT_DIR LOG_TOP

RENAME_FILE MAKE_DIR WRITE_DIR
TREE_DIR BACKUP_TAPE EDIT_FILE
UNPACK_FILE PACK_FILE LOG_TREE
COPY_TREE MOVE_TREE UNPACK_TREE
FIND_DIR ATTR_DIR
-
When invoked as
rfd
or
rfdsh,
it becomes this restricted shell automatically.
- -l
-
The shell is a login shell.
- -N
-
Reading the initial configuration files is omitted.
In addition,
the options described below in the description of
set
the builtin command are available.
Screen Layout
Fd
has the 3 major screen modes.
In the browser screen,
you can select from the file list and execute each command.
In the archive browser screen,
files in the archive file are listed separately by directory,
and you can browse as well as the browser screen.
In the tree screen,
you can move on the directory tree and select the directory path.
In all screen modes,
each
3
lines on the top/bottom of the screen are used for the various information of
fd.
The top information lines sometimes become
4
lines.
The screen layout is the following.
- line#
-
Description
- 1
-
The title line.
The clock at the right end is updated every
10
seconds.
- 2
-
The information line.
It displays information in this order:
the current page (and the total pages),
the number of marks (ant the total marks),
the sorted type,
the pattern string for file search.
- 3
-
The path line.
It displays the fullpath of the current directory.
In the archive browser screen,
it displays the fullpath of the archive file
and the current path in the archive.
- 2 (optional)
-
The file size information line.
It displays the total size of the marked files in the directory
(and the total size of all files),
the total capacity and the free size of the file system
including the current directory.
This line appears by
SIZEINFO
the internal variable setting.
When this line is displayed,
The information line and the path line are displayed 1 line under each.
- bottom - 2
-
The stack line.
It displays files temporarily which you push in stack,
when arranging files.
- bottom - 1
-
The function line.
It displays the operations of function keys.
- bottom
-
The status line.
It displays the status of the file on the cursor position.
It also displays warning messages when command is executed with some troubles.
Internal Commands
You can use the following internal commands on
fd.

Internal Commands Description
The detail of each internal command is the following.
Internal commands with similar function are described together.
-
- Move cursor
-
Move a cursor.
- Turn page
-
Turn to the previous/next page,
when files are not completely held in a screen.
Also if you try to move out of the page with Cursor move,
the page will be turned.
- Move to the top/bottom
-
Move a cursor to the top/bottom of the file list.
When the list is not held in a screen,
the page is turned.
- Shift filename
-
Shift the displayed string of filename on the cursor position,
when the filename is longer than the prepared column width.
It is displayed as shifted to right/left by 1 character.
The display of the status line is also shifted simultaneously.
- Change layout
-
Change the number of columns into each value.
There are usually
2
columns per screen.
As the column width per file is changed according to the number of columns,
the displayed information is also changed.
- Mark file
-
Mark the file on the cursor position.
You cannot mark any directory.
[Space]
marks and moves down a cursor.
[^Space]
also marks and moves down a cursor,
but doesn't turn the page.
[Home]
marks all the files,
[End]
marks all the files reversely.
[*]
additionally marks the file which matches the wildcard.
You must input the wildcard string whenever you push
[*].
Marked files are used as the target of
ATTR_FILE,
COPY_FILE,
DELETE_FILE,
MOVE_FILE,
UNPACK_FILE
and the user defined command macros.
- Change directory
-
[Return]
changes the current directory
to the directory on the cursor position.
If you want to change it to the parent directory,
you should move a cursor to the file of ".." and push
[Return],
or simply push
[Bs].
[\]
changes the current directory to the root directory.
- Push/pop file stack
-
[Del]
pushes the file on the cursor position to the file stack,
and temporarily deletes the file from the file list screen.
You can push files to the file stack up to
5
files.
[Ins]
pops the file from the file stack
and insert it on the cursor position.
The last pushed file is popped first.
But this order is expediently displayed in
fd,
and it is reset by Directory move.
- Redraw screen
-
Redraw the file list screen
by rereading the information of the current directory.
It is useful when some other process add/delete files,
or when something break the screen display.
Moreover,
when you use the terminal which doesn't raise
SIGWINCH
signal at changing the screen size (like
kterm(1)
on HP-UX etc.),
you must intentionally redraw after you change the screen size.
- Change logical directory (Logdir)
-
Change the current directory to the inputted pathname.
When you input the pathname which starts with '/',
it means not the relative move but the absolute move.
When you input the pathname ".",
the pathname of the current directory is adjusted into absolute expression.
Except this case,
the current directory always is shown as the virtual pathname,
by reason of a link and so on.
When you input the pathname "?",
you can move to the current directory when
fd
was invoked.
When you input the pathname "-",
you can move to the last visited directory.
Moreover,
When you input the pathname "@" in floppy drive,
you can move to the directory on UNIX file system,
where you existed before moving to floppy drive.
(UNIX)
(Note:
This command is called as "Loddsk" in the original FD on MS-DOS,
which is short for "LOGical DiSK drive".
This "logical" means the drive name prefixed to pathnames,
and it is virtually named against "physical disk drive".
On UNIX,
since "logical disk drive" never means pathname nor directory,
this command name "Change logical directory" is not suitable.
But this name is expediently inherited from the original version.)
- Execute file (eXec)
-
Execute the file on the cursor position with some parameters,
as the child process.
The cursor position in command line exists
after the filename in case of the executable file,
and before the filename except it.
You should fill suitable parameters or command name in each case.
The up/down cursor keys can provide the command history
which you executed before.
On MS-DOS version,
the LFN form filename in the command line
which is quoted with the quotation mark "
is automatically replaced into 8+3 form filename before execution.
In this case,
when there is the filename described by the string quoted with ",
this string is always replaced into 8+3 form filename after deleting ",
otherwise it is never replaced including ".
- Copy file (Copy)
-
Copy the file on the cursor position to the specified directory.
When the cursor position indicates a directory,
its contents are copied recursively.
When some files are marked,
the target is not the file on the cursor position but the marked files.
When the same named file exists in the destination,
you can select the operation from the following:
"Update (by timestamp)",
"Rename (each copied file)",
"Overwrite",
"Not_copy_the_same_name",
"Forward".
If you select "Forward",
you should specify the directory as the destination to forward.
All files which have the same names are moved to the specified directory.
- Delete file (Delete)
-
Delete the file on the cursor position.
No directory can be deleted.
When some files are marked,
the target is not the file on the cursor position but the marked files.
When you don't have write permission on the file,
you are confirmed for security.
- Rename file (Rename)
-
Rename the file on the cursor position.
You cannot rename to the same name as any existent file.
When you specify the pathname with some directory name,
it is also moved to the directory.
- Sort file (Sort)
-
Sort files in the current directory.
You can select the sorted type from the following:
"fileName", "Extension", "Size", "Timestamp", "Length (of filename)",
and specify "Up (incremental order)" or "Down (decremental order)".
When the sorted type before sorting is the one except "No chg (not sort)",
the choice will include "No chg".
When you sort after sorting another sorted type,
the previous sorted result is based in sorting.
This sorting has a priority except specified type,
the directory is always precedes any file,
except for the case of "No chg".
In case of "Length",
files which have the same filename length are sorted in order of their names.
But this sorting is expediently displayed in
fd,
and it is reset by Directory move.
- Find file (Find)
-
Find the files matching the wildcard, and display only them.
The filename which starts with '.'
doesn't match the wildcard which starts with '*' nor '?'.
If you want to cancel the File find,
you should move the current directory,
or do
FIND_FILE
again and input a null line.
When the current directory has the files
which have the extension registered to associate with an archive browser,
the string which starts with '/' is used
to find not the filename but the filename in archive files,
and only the archive files which contain matched files are displayed.
This function is available in the archive browser.
After Find file,
you can not do
WRITE_DIR.
- Display tree screen (Tree)
-
Display the directory tree based on the current directory.
You can select the directory in the tree screen,
to move the current directory.
- Edit file (Editor)
-
Edit the file on the cursor position.
The editor is used referring
EDITOR
the internal variable,
or referring
EDITOR
the environment variable when the internal variable is undefined.
- Unpack file (Unpack)
-
Unpack the archive file on the cursor position into the specified directory.
In builtin configuration,
you can unpack only the tar file and its compressed file
and the LHa compressed file.
You can describe configurations in the initial configuration file
to support archivers except these.
- Change attribute (Attr)
-
Change the file access mode,
the timestamp and the owner/group of the file on the cursor position.
When some files are marked,
the target is not the file on the cursor position but the marked files.
In case of the marked files,
you must select the mode, the timestamp or the owner/group,
before changing it all together.
When you input the mode,
cursor keys move a cursor to the position you want to change,
[Space]
reverses the attribute on the position.
You should notice that
the attribute of the execution bit is not a binary toggle but a triple toggle,
which includes setuid bit, setgid bit and sticky bit respectively.
If the target is the marked files,
[m](Mask)
will mask a bit on the cursor position with
'*',
to keep the value of the original file attribute.
When you input the timestamp,
you move a cursor to the position you want to change,
and input a numeric value.
When you input the owner/group,
you move a cursor to the position for each name,
and input a name or a ID value with
[Space].
You can use the completion for a user name and a group name to input each name.
Finally,
[Return]
executes the change.
You can cancel with
[Esc].
Be careful that the limit check of date is not perfect.
Moreover,
[a](Attr),
[d](Date),
[t](Time),
[o](Owner)
and
[g](Group)
move a cursor
to the each beginning of input line.
On the OS which has the attribute of file flags,
you can change the file flags as well as the mode.
In this case,
[f](Flag)
move a cursor
to the beginning of input line of file flags.
But the value of flags which you can change is based on your permission.
- File system information (Info)
-
Display the information of the specified file system.
When the inputted pathname is not the special file
which indicates a file system,
the information of the file system including the pathname is displayed.
- Move file (Move)
-
Move the file on the cursor position to the specified directory.
When the cursor position indicates a directory,
the directory itself is moved.
When some files are marked,
the target is not the file on the cursor position but the marked files.
When the same named file exists in the destination,
you can select the operation as well as
COPY_FILE.
When the destination belongs to the different file system,
copy and delete are just executed continuously.
- Delete directory (rmDir)
-
Delete the directory on the cursor position recursively.
When the directory in a symbolic link,
only the link is deleted and the linked directory has no effect.
- Make directory (mKdir)
-
Make the sub directory on the current directory.
When the inputted sub directory string includes '/',
which is the pathname delimiter,
it goes on making directory recursively
until the directory described by the string is finally created.
When you input the pathname which starts with '/',
the directory is made not on the current directory
but on the absolute path described.
- Execute child process (sHell)
-
Execute the inputted command string as the child process,
by handling the internal shell.
You can refer the command history and use automatic LFN replacement,
as well as
EXECUTE_FILE.
When you push only
[Return]
without any input,
the user shell which is described by
SHELL
the internal variable or the environment variable is invoked.
In this case,
you should input "exit" to return to
fd.
When the value of
SHELL
is
fdsh,
the internal shell is executed as the interactive shell.
However,
when there is the same command name as a builtin command or a internal command,
the builtin command or the internal command are executed
instead of the external command.
You can refer the clause of `Builtin Commands'
for the details of the builtin command.
- Write directory (Write)
-
Write the displayed directory.
The gap between files on the directory entry is filled.
When it is executed after arranged by
PUSH_FILE,
POP_FILE
and
SORT_DIR,
the result is written.
When the displayed directory doesn't belong to
the hierarchy under your home directory,
you are confirmed for security
whether if any other user doesn't use the directory.
Since it is insecure,
you cannot write the NFS mounted directory and some special directories.
If you execute the internal command which arranges the file order,
and then try to execute the internal command which will break that order,
you will be confirmed whether if you write the directory or not,
just before the internal command is executed.
For this function,
you can write the directory
without intentionally executing this Directory write command.
But when the displayed directory is not under your home directory,
this confirmation is not done.
- Backup tape (Backup)
-
Backup the file on the cursor position into the specified storage device.
When the cursor position indicates a directory,
all of its contents is backuped.
When some files are marked,
the target is not the file on the cursor position but the marked files.
Tar(1)
is used for backup.
When you specify the filename except special files indicates devices
as input of the device name,
the archive file is created with that filename.
- View file (View)
-
View the file on the cursor position.
The pager is used referring
PAGER
the internal variable,
or referring
PAGER
the environment variable when the internal variable is undefined.
- Pack file (Pack)
-
Pack the file on the cursor position into the specified archive file.
When the cursor position indicates a directory,
all of its contents is packed into the archive file.
When some files are marked,
the target is not the file on the cursor position but the marked files.
According to the extension of the inputted archive file,
the associated archiver is automatically selected.
In builtin configuration,
you can pack only the tar file and its compressed file
and the LHa compressed file.
You can describe configurations in the initial configuration file
to support archivers except these.
When you use
tar(1),
you may sometimes be unable to pack a lot of files at once,
because of the maximum parameter length which can be given at once.
In those case,
you can create the archive file with
BACKUP_TAPE.
- Operations with tree
-
[L],
[C],
[M]
and
[U]
can make you select the pathname
from the directory tree instead of the string input.
They execute the internal command equivalent to
LOG_DIR,
COPY_FILE,
MOVE_FILE
and
UNPACK_FILE,
respectively.
- Find file recursively
-
Find the file matching the wildcard recursively under the current directory,
and move the directory where the found file exists.
When the cursor position indicates a directory,
it find the file under the directory on the cursor position
instead of the current directory.
You will be confirmed for each matching file whether if you move or not,
and you can select
[n](No)
unless the target file is displayed.
- Change attributes recursively
-
Change attributes the directory on the cursor position revursively.
As well as changing attributes of the marked files,
you must select the mode, the timestamp or the owner/group,
before changing it all together with each file under the directory.
When you input the mode,
you should notice that
the attribute of the execution bit is not a triple toggle but a 5-states toggle,
which includes
'X'
and
'!'.
'X'
means setting the bit
only if the object is a directory or some execution bits are set.
'!'
also means unsetting the bit
only if the object is a directory or some execution bits are set.
[m](Mask)
will mask a bit on the cursor position with
'*',
to keep the value of the original file attribute.
- Invoke launcher
-
[Return]
executes the operation according to
the extension of the file on the cursor position,
unless the cursor position indicates a directory.
In builtin configuration,
the archive browser is registered with the tar file and its compressed file
and the LHa compressed file.
You can describe configurations in the initial configuration file
to register launchers except these.
When the file on the cursor position has the unregistered extension,
it will behave as same as
VIEW_FILE.
In the archive browser,
the registered launcher is available,
so that you can invoke the archive browser recursively.
- Switch symbolic link mode
-
In case of the symbolic link file,
the file information displayed in the file column and the status line
shows not the status of its referential file but the status of the link itself.
It switches to show the status of the referential file.
(UNIX)
In the mode of showing the status of the referential file,
'S'(Symbolic
Link)
is displayed on the left end of the function line.
- Switch file type symbol mode
-
Switch to display the symbol which means the file type
after the filename in the file list,
like as the display in
-F
option of
ls(1).
It is toggle to switch if display the symbol or not.
The each symbol means the following.
-
/ directory
@ symbolic link
* executable file
= socket
| FIFO
-
(MS-DOS version and the floppy drive)
/ directory
* executable file
= system file
| label
-
In the mode of displaying the file type symbol,
'T'(Type)
is displayed on the left end of the function line.
- Switch dot file display mode
-
Switch not to display the file whose filename starts with '.' in the file list.
It is toggle to switch if display the dot file or not.
In the mode of not displaying the dot file,
'H'(Hidden)
is displayed on the left end of the function line.
- Switch file flag display mode
-
Switch to display the file flag, which exists in some OS,
instead of the file mode on each file.
It is toggle to switch if display the file flag or the file mode.
This is not available on any OS without the file flag.
The each symbol means the following respectively.
(UNIX)
-
A Archived
N Nodump
a system Append-only
c system unChangeable (immutable)
u system Undeletable
a user Append-only
c user unChangeable (immutable)
u user Undeletable
-
In the mode of displaying the file flag,
'F'(Flags)
is displayed on the left end of the function line.
- Search file
-
Search the current directory incrementally for the filename,
with moving a cursor.
When you execute this command, to switch to the search mode,
a prompt appears in the function line.
You can input the filename in this prompt,
and a cursor will move to the filename matching the string
which is already inputted at that present.
[Esc]
switches to the normal mode.
- Split window
-
Split the current window.
When you split a window in the normal non-split window mode,
it will be the split window mode in which the screen is split into 2 windows vertically.
In the split window mode,
you can operate works individually on each window.
When you split a window in the split window mode,
the current working window is split into 2 windows vertically.
You can make split windows up to
5.
- Change window
-
Change effective window to the next in the split window mode.
When the current window is the last,
the first window will be effective.
In the non-split window mode, it is ineffective.
- Widen window
-
Widen the current window size in the split window mode,
to narrow the next window size.
When the current window is the last,
the first window size will be narrowed.
In the non-split window mode, it is ineffective.
- Narrow window
-
Narrow the current window size in the split window mode,
to widen the next window size.
When the current window is the last,
the first window size will be widened.
In the non-split window mode, it is ineffective.
- Kill window
-
Kill the current window in the split window mode,
to join it to the previous window.
When the current window is the first,
it will be joined to the last window.
If the result number of windows is one,
it will be the non-split window mode.
In the non-split window mode, it is ineffective.
- Invoke customizer
-
Invoke the customizer which interactively changes the configurations
to be set up by the internal variable and the builtin command.
While the configurations which is set up here is reflected immediately,
you must intentionally save configurations in the customizer
if you want to reflect in the initial configuration file.
- Display help
-
Display the list of the current key bindings and their command descriptions.
When the list is not completely held in a screen,
it prompts for every screen.
In case of the circulated executable binary file,
this screen shows
the E-mail address of the circulation manager in the function line.
Please contact here when something will happen.
- Quit (Quit)
-
Quit from
fd.
Commands
In
EXECUTE_SH
and the initial configuration file,
you can use the internal commands described above
and the builtin commands described below,
as well as the external commands.
With these commands,
a pipeline can consist of one or more commands separated by
|
or
|&.
|
connects the standard output of the previous command
to the standard input of the next command.
|&
connects both the standard output and the standard error output
of the previous command
to the standard input of the next command.
The exit status of a pipeline is the exit status of the last command.
You can start a pipeline with
!,
then the exit status of a pipeline will be
the logical NOT of the exit status of the last command.
Moreover,
a command list can consist of one or more pipelines separated by
;,
&,
&|,
&&,
||.
This command list can end with
;,
&
or
&|.
These separators mean the following.
-
- ;
-
Execute commands sequentially.
- &
-
Execute commands synchronously,
not waiting for the preceding pipeline to finish.
(UNIX)
- &|
-
Same as
&,
except to immediately
disown
the job.
(UNIX)
- &&
-
Execute the following pipeline
only if the preceding pipeline returns a
0
exit status.
- ||
-
Execute the following pipeline
only if the preceding pipeline returns a

form to open the following TCP sockets,
according to the string of
scheme.
The authentication of your OS will restrict specifying the accepting port.
(UNIX)
-

-
This socket is connected to the remote host specified by
host
with the TCP port number specified by
port.

When the line ends with
'\',
it is referred as continuing into the next line,
so that you can split a long line with this.
Builtin Commands
Fd
has the following builtin commands.
These builtin commands can be used in
EXECUTE_SH
and the initial configuration file.
- if list then [elif list then list] ... [else list] fi
-
The
list
of
if
clause and
elif
clauses are executed in order,
and if each exit status is a 0,
then the
list
of
then
clause associated with it is executed and the
elif
clauses after it are ignored.
If no
list
of
if
clause nor
elif
clauses return a 0, the
list
of
else
clause is executed.
If no
list
of
then
clauses nor
else
clause is executed,
then
if
returns a
0
exit status.
- while list do list done
-
The
list
of
while
clause is executed repeatedly,
and while its exit status is 0, the
list
of
do
clause is executed repeatedly.
If the
list
of
do
clause is never executed,
then
while
returns a
0
exit status.
- until list do list done
-
The
list
of
until
clause is executed repeatedly,
and while its exit status is NOT 0, the
list
of
do
clause is executed repeatedly.
If the
list
of
do
clause is never executed,
then
until
returns a
0
exit status.
- for NAME [in value ...] do list done
-
NAME
the internal variable is substituted for values of
value
one by one, and
list
is executed according to the each value.
If
in
value
is omitted,
then each positional parameter is substituted one by one.
- case word in [pattern [| pattern] ... ) list ;;] ... esac
-
The string
word
is compared with the each
pattern,
list
associated with the
pattern
which first matches it is executed.
- (list)
-
Execute
list
in a sub shell.
- { list; }
-
Execute
list
in the current shell.
- NAME=[value] [com ...]
-
Define a internal variable which is available only in
fd.
It substitutes the value (string)
value
for
NAME
the internal variable.
When you describe the command
com
after the definition of a variable,
com
is executed on the state
where this variable is regarded as the environment variable.
In this case,
the definition of
NAME
is not remain as the environment variable nor the internal variable.
If
value
is omitted,
the value of
NAME
the internal variable is defined as a null.
If you want to delete the definition of a internal variable,
use
unset
the builtin command.
- name() { list; }
-
Define a function whose body is
list,
as the name of
name.
The defined function can be used in the command line of
EXECUTE_SH
and each command macro described below.
You can use the positional parameter
$n
in each description of
list,
which indicates the argument when the function is invoked.
$0
is
name
itself, and
$1-$9
indicates each argument.
Although you cannot omit
{ }
and
list,
you can omit
{ }
before/after
list
which consists of a single command.
If you want to delete the definition of a function, use
unset
the builtin command.
- !num
-
Execute the command
which has the history number specified with the numeric value
num.
When
num
is negative value,
it executes the command
which has the history number as the current history number minus
num.
- !!
-
Execute the previous command.
This is synonym for
!-1.
- !str
-
Execute the command history
which starts with the string
str.
- : [arg ...]
-
No effect.
But it evaluates
arg
and performs redirection.
- . file
-
- source file
-
Read and evaluate commands from
file.
File
must exists on the directory which
PATH
includes,
or be described with pathname.
The each line format is based on the format of
EXECUTE_SH.
You can describe this in the file as nesting.
- accept [fd]
-
Accept the connection with the file descriptor indicated by
fd,
and the connected socket will be assign to
fd
of the same file descriptor.
At the same time,
the accepted socket will be closed.
When
fd
is not the redirection as the form of
bind://,
this command will be failed.
In comparison with the redirection as the form of
accept://,
the shell can receive controls before establishing connection to negotiate the TCP port number with the remote host in advance.
(UNIX)
If
fd
is omitted,
the connection will be accepted with the standard input.
- addcr [-1] [file]
-
Output the string read from the file specified by
file,
line by line.
The newline of each line is unified into CR-NL (\r\n).
It is useful to pipe the output to some socket.
If
file
is omitted,
it is regarded as the standard input is specified.
If
-1
is specified,
it will output just 1 line and exit.
- alias [name[=com]]
-
Define a alias whose body is
com,
as the name of
name.
The defined alias can be used in the command line of
EXECUTE_SH
and each command macro described below.
The alias substitution is performed recursively.
If
com
is omitted,
the alias of
name
is displayed.
If both
com
and
name
are omitted,
all the current alias definition list is displayed.
- arch ext [pack unpack]
-
Register the archiver command associated with the archive file
which has
ext
the extension.
The pack command is specified as
pack,
and the unpack command is specified as
unpack,
using the macro representation quoted with ".
When
ext
starts with
/,
uppercase/lowercase is ignored in the comparison of any extension.
If both
pack
and
unpack
are omitted,
the archiver command registration for
ext
the extension is deleted.
- bg [job]
-
Continue the execution of the job specified with
job
in the background.
The following format is available to specify a job.
(UNIX)
-
%
%+ the current job
%- the previous job
%n the job with job number n
%str the job whose command line starts with str
-
But, you must describe these
%
in the command line of
EXECUTE_SH
as the duplicated expression, such as
%%,
for the reason of the parameter macro function described below.
If
job
is omitted,
the current job is continued in the background.
- bind c [com1 [com2] [:comment]]
-
Bind the command
com1
to the key
c.
When you want to specify a control character for
c,
you can prefix
^
into 2 characters,
such as ^A.
When you want to specify a character with the META key
(or the ALT key on MS-DOS version),
you can prefix
@
into 2 characters,
such as @a.
When you want to specify a function key and a special key,
you can use each identifier described in
keymap
command after,
such as F10.
Or you can describe the escape sequence,
such as
\n
and
\e,
and the octal expression,
such as
\ooo.
In case of binding the internal command of
fd,
you can the command identifier as it is.
When you want to define the internal command with some arguments
or define the command in the macro representation,
you should describe the string quoted with ".
If
com2
is not omitted,
com2
is executed when the cursor position indicates a directory.
When the key
c
is the function key of F1-F20,
if you describe
comment
prefixed with
:
trailing the command description,
you can change the display of associated part in the function line into
comment.
However, note that,
with the key binding for the control key,
the configuration in the edit mode described below is prior to the key binding.
If both
com1
and
com2
are omitted,
the registration of key binding for the key
c
is deleted.
- break [n]
-
Exit from the loop,
it is used in the
for
statement and so on.
If
n
is specified,
it breaks
n
levels from the loop.
- browse [-@ file]
-
- browse com [-ftbie arg] [-p com2] [-dn {noprep,loop}] ...
-
Execute
com
the command,
and invoke the archive browser who receives its output.
You should the macro representation quoted with " as
com.
-f,
-t,
-b,
-i
and
-e
options are the same as the one for
launch
the builtin command.
In case that multiple
coms
are specified,
the next
com
the command is executed one after another
when you select each files in the archive browser,
and the formats and patterns described after each
com
the command are adopted.
In order to return to the previous level of archive browser,
you should select the file named as
..
or push the key
[Bs].
Or you can use
QUIT_SYSTEM
the command to escape from all of the archive browsers invoked by
browse.
You must describe
-f
option, except for the last
com
the command.
When the last
com
has no
-f
option,
the command has been just executed instead of invoking an archive browser,
and then will return to the previous archive browser when it is done.
When you specify
-p
option,
the execution of
com2
the command precedes the execution of the next
com
the command when you select a file.
While
com
is executed in the sub shell for a pipeline,
com2
is executed in the current shell
to inherit the values of internal variables set in this command after
com2
has been done.
The filenames which is selected toward this level of archive browser
are held in positional parameters sequentially,
and the last selected filename is held in
$1.
These parameters will be newly set whenever you select a file,
so that they are reset in sequential order when you select the next file
even if you replace them with
set
or
shift
the builtin command.
-d
and
-n
options specify a control if the selected file is a directory or not respectively.
When you specify
noprep,
com2
specified by
-p
option is not executed.
When you specify
loop,
you don't step the next
com
the command but the same
com
the command again.
And when you think troublesome to describe too many arguments for
browse,
you can specify
file
the file in which some arguments are described with
-@
option.
You can describe
-@
option in any place of arguments,
the arguments described in
file
are inserted in the place where
-@
is described.
If you specify
-
as
file,
arguments are read from the standard input instead of the file.
You should describe arguments in
file
with spaces or newlines as separator.
The null line and the line started with
#
will be ignored.
When you describe
-@
option in
file,
the argument file is referred recursively.
- builtin arg ...
-
Execute
arg
as a simple builtin command.
When the same named function is defined,
the function will not be executed.
- cd [-LP] [dir]
-
- chdir [-LP] [dir]
-
Change the current directory in
fd
to
dir.
If
dir
is omitted,
it moves to the directory indicated by
HOME
the internal variable.
If you specify the pathname as ".", "?", "-", "@",
it behaves like as
LOG_DIR.
If
-L
is specified,
the logical pathname following symbolic links is used.
If
-P
is specified,
the physical pathname following no symbolic links is used.
Otherwise,
the
physical
option for
set
the builtin command is effective.
- checkid [file ...]
-
Calculate the unique ID of the specified file and display it,
according to the MD5 algorithm in RFC1321.
When you specify multiple
files,
the IDs of all specified files are calculated and displayed.
When you specify nothing,
the ID of running
fd
itself is displayed.
Since this algorithm is guaranteed to be secure,
it is available to confirm the identity of files.
- cls
-
Clear the screen.
- command [-p | -v | -V] arg ...
-
Execute
arg
as a simple command.
When the same named function is defined,
the function will not be executed.
If
-p
is specified,
the default value of
PATH
is used to search the path.
If
-v
is specified,
the absolute path for
arg
is displayed
instead of executing
arg.
In this case,
arg
the builtin command will cause simply its name.
If
-V
is specified,
verbose description for
arg
is displayed as same as
type.
- continue n
-
Resume the next iteration in the loop,
it is used in the
for
statement and so on.
If
n
is specified,
it resumes the next iteration in the loop
n
- 1 levels
out of the loop.
- copy [-ABVY-Y] src [-AB] [+ src2 [-AB] [+ ...]] [dest [-AB]]
-
Copy the file indicated by
src
into the file or the directory indicated by
dest.
When
dest
indicates a directory,
the filename in the destination is
src.
If
dest
is omitted,
it is copied into the current directory.
You can specify multiple source files by describing to separate them with
+,
or by using the wildcard.
When you separate them with
+,
those files are concatenated and copied.
When you use the wildcard,
they are copied one by one in case that the destination is a directory,
and they are concatenated in case that the destination is a file.
When you specify
-A,
it is treated as the ASCII text file.
When you specify
-B,
it is treated as the binary file.
When you specify
-V,
it is verified to copy.
When you specify
-Y,
it doesn't prompts for confirming to overwrite into the destination.
When you specify
--Y,
it prompts for confirmation before overwriting into the destination.

as an option prefix for compatibility with COMMAND.COM.)
- del [-P] file
-
- erase [-P] file
-
Delete the files indicated by
file.
You can specify multiple files by using wildcard.
When you specify
-P,
it prompts for confirmation before deleting files.

as an option prefix for compatibility with COMMAND.COM.)
- dir [-[-]PWSBLV4] [-A[DRHSA-]] [-O[NSEDGA-]] [dir]
-
List files and sub directories in the directory indicated by
dir.
If
dir
is omitted,
the information in the current directory is listed.
When you specify

-S,
it lists files in all sub directories.
When you specify
-B,
it displays only names of files and directories.
When you specify
-L,
it uses lowercase.
When you specify
-V,
it lists the verbose information.
When you specify
-4,
it displays year with 4 digits.
And you can prefix
-
to any option letter to override the option.
(MS-DOS version requires to use
/
instead of
-
as an option prefix for compatibility with COMMAND.COM.)
- dirs
-
Display the list of the current directory stack.
Pushd
and
popd
the builtin command can load/unload directories onto the directory stack.
- disown [job]
-
Remove the job specified with
job
from the shell control.
The job to be
disowned
cannot be controlled by
jobs,
fg
and
bg.
If invoked as a login shell,
any jobs not to be
disowned
will be forced to exit when the shell finish.

the current job is removed from the shell control.
- dtype file
-
Display the contents of the file indicated by
file.
- echo [-nN] [arg ...]
-
Echo
arg
to the standard output.
When you don't specify

When you specify
-N,
the outputted newline becomes CR-NL (\r\n).
See
echo(1)
for details.
- enable [-n] [arg ...]
-
Enable
arg
as a builtin command.
When you specify
-n,

all of the enabled or disabled builtin commands is listed.
- eval [arg ...]
-
Evaluate
arg
and execute the results.
- evalmacro [arg ...]
-
Evaluate parameter macros included in
arg
and execute the results.
Since
eval
doesn't evaluate any parameter macro,
you should choose them according to uses.
When in the function,
you cannot use any parameter macro,
then you need this command to extract parameter macros.
- exec [com [arg ...]]
-
Execute
com
in place of the execution of
fd.
You can specify
arg
as arguments of
com.
- exit [n]
-
Exit from
fd.
When you specify

it exits with the exit status
n.
- export [NAME[=[value]] ...]
-
Mark
NAME
the internal variable to be inherited to child processes as the environment variable.
Since then,
the definition of
NAME
can be referred in any child process.
When you
export
the undefined internal variable,
it doesn't become the environment variable
until the internal variable is defined.
When you want to define the value at the same time,
you should specify
value.
If only
=
is specified and
value
is omitted,
the value of
NAME
the environment variable is defined as a null.
If no argument is specified,
all of the
exported
environment variables is listed.
When you want to delete the definition of the environment variable,
you can use
unset
the builtin command.
- false
-
Only return with a
1
exit status.
- fc [-l | -s [old=new ...]] [-nr ] [-e editor] [first [last]]
-
List or edit command histories.
First
and
last
select the range of command histories.
This specification can be described as a numeric value or a string.
A positive value means the command history number,
and a negative value means the command history
which has the history number as the current history number minus the value.
A string mean the command history which starts with the string.
If
-n
is specified,
command histories are listed without their history numbers.
If
-r
is specified,
command histories are listed in reverse order.
If
-e
is specified,
the editor named by
editor
is used to edit command histories,
otherwise the editor specified by
FCEDIT
or
EDITOR
the internal variable is used.
When
-l
is specified,
selected command histories are listed to the standard output.
In this case,
omitting
last
means to specify the current history number,
and also omitting
first
means to specify
-16.
When
-s
is specified,
the command history selected by
first
is executed immediately.
In this case,
omitting
first
means to specify the current history number.
The first occurrence of the string
old
in the command history will be replaced by the string
new
before execution.
When neither
-l
nor
-s
is not specified,
selected command histories are edited,
and then each edited commands are executed one by one
with display in the standard output.
In this case,
omitting
last
means to specify
first,
and also omitting
first
means to specify the current history number for both.
- fd [directory [directory2]]
-
Invoke
fd
from the internal shell.
If you specify
directory,
the current directory is moved to the directory initially.
If you specify
directory2,
the split window mode is invoked,

You can return to the internal shell by
QUIT_SYSTEM.
It is effective only when it is invoked as
fdsh.
- fg [job]
-
Continue the execution of the job specified with
job
in the foreground.
The following format is available to specify a job.
(UNIX)
-
%
%+ the current job
%- the previous job
%n the job with job number n
%str the job whose command line starts with str
-
But, you must describe these
%
in the command line of
EXECUTE_SH
as the duplicated expression, such as
%%,
for the reason of the parameter macro function described below.
If
job
is omitted,
the current job is continued in the foreground.
- getfreq [file]
-
Output the contents of the translation frequency file,
specified by
file,
to the standard output for the users Kana-Kanji translation learning.
The output format provides one record per line,
which consists of "Yomi-Gana", "word" and "frequency" separated by tab.
You can use this output as the argument of
setfreq
to import the frequency information.
If
file
is omitted,
it is regarded as the translation frequency file specified by
FREQFILE
the internal variable.
(UNIX)
- getkey [num]
-
Get the key code sequence for the pushed key.
It prompts after executed,
and displays the key code sequence for the key which you push to specify.
It continues until you push any key
num
times.
When
num
is more than
1
time,
you can stop it with pushing
[Space].
When
num
is
0
time,
it continues forever until
[Space]
is pushed.
The displayed sequence can be used as the key code sequence for
keymap
command.
(UNIX)
If
num
is omitted,
it is regarded as
1
time is specified.
- getopts optstr NAME [arg ...]
-
Used to parse the optional parameters from a sequence of
arg.
The valid characters as option is described in
optstr.
An option character which needs an argument is described with following
:
in
optstr.
Each time
getopts
is invoked,
the new option character parsed from
arg
is substituted for
NAME
the internal variable.
When the option has an argument,
the argument is substituted for
OPTARG
the internal variable.
And the index of the next parameter is substituted for
OPTIND
the internal variable every time.
The value of
OPTIND
is initialized to
1
whenever the shell is invoked,
another parsing of option parameters needs initializing
OPTIND

On the PC-UNIX environment which is worked on PC,
specifying the string
HDD
or
HDD98
instead of
hd,
sc,
cl,
can register the MS-DOS partition on the hard disk
for the PC/AT compatible machine or PC-9800 series.
In this case,
You should describe the device file
as the device name prepared per the physical drive unit
rather than the device name prepared per the partition (slice).
The MS-DOS partitions included in the drive unit
are automatically expanded to the drive name after the drive name
c.
When no MS-DOS partition is included in the specified drive unit,
this command is ignored.
You can confirm what drive name is valid by

Tree Screen
Since representing the whole file system in tree structure takes too many time,
only the directories which are direct ancestors
and the direct sub directories are displayed,
first in the tree screen.
In the directories which are direct ancestors,
the other sub directories (if exists)
are grouped as "
...".
These grouped sub directories will be expanded automatically
when a cursor is placed on its position.
The sub directories which are not expanded yet are represented with
'>'
trailing the filename,
which shows as they are.
Such directory is never expanded until it is required to expand explicitly,
then you should expand it by the following key inputs
before moving to any hidden sub directory.
In the tree screen,
the following key inputs are available.
-
- Up, Down
-
Move a cursor.
- Right
-
Expand the sub directory on the cursor position.
- Tab
-
Expand the sub directory on the cursor position recursively.

Moving to the floppy drive is also available.
- ^L
-
Redraw the tree structure.
- Return
-
Select the directory.
- Esc
-
Cancel.
When directories are recursively expanded,
the machine operation is so late that it maybe seems to freeze.
In this case,
you can input any key while operating.
If key input is recognized while expanding directories,
expanding has been stopped at that moment in spite of not finishing.
Even if key repeat keeps effective,
any operation will be delayed for this function.
Archive Browser
When the launcher is invoked on the position of the file
whose extension is registered to associate with an archive browser,
the archive browser screen has come.
In this screen,
you can browse files in the archive file as well as in the normal directory.

%B Field which indicates a major device ID
%b Field which indicates a minor device ID
%/str/ Field which indicates a type is directory
when this field string is str
(case insensitive)
%!str! 0 or more continuous fields
which consists of the string str
(case insensitive)
%f Field which indicates a filename
%x Field which is needless (ignored)
%% % itself
\n Newline
Space Tab 0 or more characters of spaces or tabs
In this description,
the field means the area separated by spaces, tabs or newlines.
When the string which indicates each information
is separated by these characters,
you can simply describe the above string which indicates that field.
When the string is separated by another character,
you should describe the above string with that separator.
You can describe to indicate the field length as numeric, such as
%10a.
This example means that
the field which indicates a file mode consists of 10 characters.
If you describe it with a character
*
as the field length instead of numeric,
such as
%*f,
the string to the end of line is regarded as a field,
in which any space and tab will be ignored.
When a field may have the different meanings according to situation,
you should describe it quoted with
{ },
such as
%{yt}.
This example means that
this field indicates a creation year or a creation time.
When the information for 1 file consists of multiple lines,
you should place a
\n
on the position of newline in the format string.
For example,
the following are the format strings for the list of some archivers.
While some spaces are used here for easiness to see,
these spaces are not always necessary
because any space between fields is ignored.
- `lha l'
-
"%9a %u/%g %s %x %m %d %{yt} %f"
- `lha v' (MS-DOS)
-
"%f\n%s %x %x %y-%m-%d %t"
- `tar tvf' (BSD)
-
"%9a %u/%g %s %m %d %t %y %f"
- `tar tvf' (SVR4)
-
"%a %u/%g %s %m %d %t %y %f"
If you register archive browsers with above format,
in the builtin command of
EXECUTE_SH
or in the initial configuration file,
you can use the archive browser which is not prepared by default.
But,
if you want to execute or view files in the archive file,
you must register the archiver command for the archive file, too,
don't forget this.
On some OS,
tar(1)
may output the Japanese timestamp when
japanese
is substituted for
LANG
the environment variable.
Since
fd
cannot analyze the representation like this,
you should describe
`export LANG=C'
in the initial configuration file,
or specify
LANG
in the description of listing command,
such as
`LANG=C tar tvf'.
Floppy Drive (UNIX)
You can access the MS-DOS formatted floppy disk,
by representing to prefix "
c:" to the directory name.
But,
it is necessary to register the floppy drive
and set
DOSDRIVE
the internal variable which makes this function effective, in advance.
Each registered drive is distinguished with the drive name.
You should tag the physically different drive as the different drive name.
When the same physical drive supports multiple formats,
you can register each format with the same drive name,
or the different drive name each other.
If you tag the same drive name,
the justice of the format is tried in registered order,
so that you should register the format which you often use in the first place.
Each drive of the floppy drive has the its own current directory.
The default value of this is a root directory,
and the current directory is moved back to a root directory again
whenever you change a floppy disk.
When you describe the directory name as starting with '/' after
':',
it means the absolute path representation of that drive.
If this '/' is not exist,
it means the relative path representation
from the current directory of that drive,
don't forget this.
Regrettably,
some internal commands like as
WRITE_DIR,
INFO_FILESYS
cannot support the floppy drive.
Some filenames are renamed when they are copied from UNIX
for reason of the filename length limit.
When you use a lowercase letter as the drive name,
you can access it as the floppy drive which can treat the Long File Name (LFN)
for MS-Windows formatted floppy disk.
In this case,
you can copy a file with a long filename on UNIX as it is.
But,
when the UNICODE translation table
fd-unicd.tbl
does not exist in the same directory as the invoked
fd
exists,
any Kanji filename cannot be treated as LFN representation.
Reversely,
when you use a uppercase letter as the drive name,
LFN is ignored and 8+3 formed filename is treated.
MS-DOS version inherits this specification by the case of a drive name.
URL Drive (UNIX)
You can access remote services on the network,
by representing the URL string as the directory name.
The URL format is
scheme://[
user[
:password]
@]
host[
:port]
/directory/.
You can specify
ftp
or
http
as
scheme.
You can specify the name or IP address of the remote host as
host.
You can specify the TCP port number as
port.
If
port
is omitted,
the default port number is used.
The default port number for
ftp
is
21,
and the default port number for
http
is
80.
You can specify account information to connect the remote host as
user
and
password.
If
user
is omitted,
the anonymous FTP connection will be used with
ftp,
or you will be queried as needed with
http.
If
password
is omitted,
you will be queried as needed.
But,
it is necessary to set
URLDRIVE
the internal variable which makes this function effective, in advance.
Regrettably,
some internal commands cannot support the URL drive,
for the sake of restrictions of the FTP and HTTP protocols or settings of the host side.
String Input
When you input the string, such as the pathname,
the following key inputs are available.
The kind of referred history differs with the input string required.
In the split window mode,
the current directory of another window is always placed
on the top of the pathname history.
- Left, Right
-
Move a cursor.
- Up, Down
-
Refer the previous histories (only commands and pathnames),
or move a cursor.
- Beg
-
Move a cursor to the beginning of string.
- Eol
-
Move a cursor to the end of string.
- Ins
-
Switch a input method to the insert/overwrite mode.
(Default value is the insert mode.)

-
Delete a string after the cursor position.
- InsLine
-
Treat the next input character as it is,
effective to input control characters.
- Enter
-
Insert a filename of the file on the cursor position.
- PageUp
-
Convert a character on the cursor position to uppercase.
- PageDown
-
Convert a character on the cursor position to lowercase.
- Tab
-
Complete a pathname, a command name or a variable name on the cursor position.
-
When there are two or more completion choices,
inputting this continuously can display the completion choice list.
Except for command line in the internal shell,
you can make a choice from this list with cursor keys and
[Return].
- ^L
-
Redraw the input string.
- ^S, ^R
-
Search the previous histories (only commands and pathnames) incrementally.
- Return
-
Decide the input,
or decide the choice in the completion choice list.
- Esc
-

The inputted string is expanded before evaluation as following.
These expansions are also valid in the string of command macros.
But these expansions are restrained
in the string quoted with the quotation mark
'.
- ~

Indicate your home directory,
when it is the beginning of filename.
- ~user
-
Indicate
user's
home directory,
when it is the beginning of filename.

Indicate the directory where the invoked
fd
is exists,
when it is the beginning of filename.
- $NAME
-
- ${NAME}
-
Indicate the value of
NAME
the internal variable or the environment variable.
When both are defined,
the internal variable is prior.
When both are undefined,
it is replaced a null.
The brace
{ }
separates
NAME
from its trailing characters.
When
NAME
is the following character,
it is replaced by the value substituted automatically by the shell.
-
- 0
-
The executable filename when invoked.
- [1-9]
-
The positional parameter.
- *
-
The all positional parameters which starts from
$1.

The process number of the current shell.
- !
-
The process number of the last executed background process.
- ${NAME:-word}
-
If the value except a null is substituted for
NAME
the internal variable or the environment variable,
it is replaced by the value,
otherwise it is replaced by
word.
- ${NAME:=word}
-
If the value except a null is substituted for
NAME
the internal variable or the environment variable,
it is replaced by the value,
otherwise
word
is substituted for
NAME
the internal variable,
and this expression itself is replaced by
word.
But you cannot substitute the value for any positional parameter.
- ${NAME:?word}
-
If the value except a null is substituted for
NAME
the internal variable or the environment variable,
it is replaced by the value,
otherwise
display
word
and exit from the shell.
If
word
is omitted,
the string
``parameter null or not set''
is displayed in its place.
- ${NAME:+word}
-
If the value except a null is substituted for
NAME
the internal variable or the environment variable,
it is replaced by
word,
otherwise it is replaced by a null.
- ${NAME-word}
-
If any value is substituted for
NAME
the internal variable or the environment variable,
it is replaced by the value,
otherwise it is replaced by
word.
- ${NAME=word}
-
If any value is substituted for
NAME
the internal variable or the environment variable,
it is replaced by the value,
otherwise
word
is substituted for
NAME
the internal variable,
and this expression itself is replaces by
word.
But you cannot substitute the value for any positional parameter.
- ${NAME?word}
-
If any value is substituted for
NAME
the internal variable or the environment variable,
it is replaced by the value,
otherwise
display
word
and exit from the shell.
If
word
is omitted,
the string
``parameter null or not set''
is displayed in its place.
- ${NAME+word}
-
If any value is substituted for
NAME
the internal variable or the environment variable,
it is replaced by
word,
otherwise it is replaced by a null.
- ${#NAME}
-
It is replaced by the length in characters of the value of
NAME
the internal variable or the environment variable.
If
NAME
is
*
or
@,
it is replaced by the number of positional parameters instead of the length of characters.
- ${NAME%word}
-
It is replaced by the string in which the smallest portion of the suffix matched by the
word
pattern is deleted from the value of
NAME
the internal variable or the environment variable.
If
NAME
is
*
or
@,
each positional parameter is replaced.
(
\
is used instead of
%
on MS-DOS version.)
- ${NAME%%word}
-
It is replaced by the string in which the largest portion of the suffix matched by the
word
pattern is deleted from the value of
NAME
the internal variable or the environment variable.
If
NAME
is
*
or
@,
each positional parameter is replaced.
(
\\
is used instead of
%%
on MS-DOS version.)
- ${NAME#word}
-
It is replaced by the string in which the smallest portion of the prefix matched by the
word
pattern is deleted from the value of
NAME
the internal variable or the environment variable.
If
NAME
is
*
or
@,
each positional parameter is replaced.
- ${NAME##word}
-
It is replaced by the string in which the largest portion of the prefix matched by the
word
pattern is deleted from the value of
NAME
the internal variable or the environment variable.
If
NAME
is
*
or
@,
each positional parameter is replaced.
- \c
-
It indicates a character
c
itself.
You can use it
when you want to use the preceding meta-character
as a character with no evaluation,
such as
~
or
$.
You can describe
\
itself as "\\".
But,
on MS-DOS version,
because
\
which is used as the pathname delimiter
must be treat as well as the normal character,
%c
is expediently used in place of
\.
The following is replaced only in the shell
which is executed by
EXECUTE_SH
and
EXECUTE_FILE.
- `list`
-
List
is executed
and this string is replaced by its standard output.
- $(list)
-
List
is executed
and this string is replaced by its standard output like as `list`.
This differs from
`list`
in the point that nested expressions are allowed.
And any meta-characters such as quotes in
list
are evaluated as it is.
- $((expression))
-
Expression
the arithmetic expression is evaluated
and this string is replaced by its result value.
You can specify numeric values,
variables and integral calculations with the following operators in
expression.
-
(unary) (binary)
arithmetic + - + - * / %
boolean ! == != < > <= >= && ||
bit operator ~ & | ^ << >>
parenthesis ( )
- ?
-
- *
-
- [
-
- ]
-
The string including these letters is pattern-matched with existent files.
When it is matched,
it is replaced by all of the matched filenames
which are sorted in alphabetical order.
-
- ?
-
Match any single character except
/.
- *
-
Match any 0 or more length string not including
/.
- **
-
Match any 0 or more length string including
/.
- [...]
-
Match any one of the characters enclosed by
[ ].
When enclosed characters include
-,
it matches any character
whose character code is between characters before/after
-.
- [!...]
-
Match any one of the characters not enclosed by
[ ].
But,
when the first character of the filename is
.,
?,
*
and
**
don't match it.
Edit Mode
When you want to use some functions bound to special keys,
such as a cursor key or a scroll key,
such a key doesn't exist in some terminals.
In such a case,
substituting the string for
EDITMODE
the internal variable can make you use some control keys as alternative to these special keys.
Since this alternative key function is prior to
the key binding by the builtin command,
the key binding is invalid for the control characters
used as the alternative keys.
The prepared edit modes are the following 3 modes.
- emacs
-
-
^P = Up ^A = Beg
^N = Down ^E = Eol ^D = Del
^F = Right ^Q = InsLine
^B = Left ^K = DelLine
^V = PageDn ^Y = PageUp ^O = Enter
^M = Return ^I = Tab ^H = Bs
^[ = Esc ^G = Esc
- wordstar
-
-
^E = Up ^A = Beg ^V = Ins
^N = Down ^F = Eol ^G = Del
^F = Right ^W = Home ^] = InsLine
^S = Left ^Z = End ^Y = DelLine
^C = PageDn ^R = PageUp ^N = Enter
^M = Return ^I = Tab ^H = Bs
^[ = Esc
- vi
-
Vi
mode has the 2 local modes: "insert mode" and "command mode",
and the function of keys are quite different with each mode.
You are in the command mode when you start to input,
then you must input any key among 4 keys which switch to the insert mode,
in order to input normal keys.
-
(command mode)
k = Up 0 = Beg
j = Down $ = Eol x = Del
l = Right g = Home
h = Left G = End D = DelLine
^F = PageDn ^B = PageUp o = Enter
^M = Return ^I = Tab ^H = Bs
^[ = Esc
(from command mode to insert mode)
i, : = only switch its mode
I = + Beg
a = + Right A = + Eol
R = overwrite
r = overwrite once
(insert mode)
^V = InsLine Esc = to command mode
-
This key binding is so particular
that it is not suitable for those who don't use
vi
editor everyday.
Kana-Kanji IME (UNIX)
You can input strings in the Kana-Kanji IME mode,
if you input the key specified by
IMEKEY
or select "Kanji"
from the pseudo terminal menu.
The translation performance will depend on the Kana-Kanji translation dictionary
fd-dict.tbl.
When it does not exist in the same directory as the invoked
fd
exists,
translation to Kanji will not be available.
The standard installed dictionary file is the Tan-Kanji dictionary,
which can support only the Tan-Kanji translation.
The dictionaly such as the pubdic,
which includes the Hinsi information,
will bring you the Tan-Bunsetsu translation.
The Ren-Bunsetsu translation is not be supported.
In the Kana-Kanji IME mode,
the following key inputs are available.
-
- Space
-
Trancelate to Kanji,
or select the next translation candidate.
- Left, Right
-
- Up, Down
-
Move a cursor in the list of the translation candidate.
- Bs, Del
-
Delete a character before the cursor position.
- Tab
-
Toggle Hiragana, Katakana, Hankaku-Kana and the direct input.
- ^L
-
Redraw the input string.
- Return
-
Decide the translation result.
- Esc
-
Cancel.
When you translate the string of the capital 4 digit hexadecimal prefixed by a capital letter,
it is regarded as the hexadecimal showing the following Kanji code respectively.
Then the menu will be displayed to select Kanji next to the Kanji code number.
-
- S
-
Shift JIS
- E
-
EUC-JP
- J
-
JIS code (JIS X0208)
- K
-
Kuten code
- U
-
UNICODE (UCS2)
When you input
[
Space]
in the state where you decide an un-translated Kana,
it is regarded as the initial reading of Kanji.
Then the menu will be desplayed to select Kanji whose reading starts with the Kana.
Parameter Macros
You can use the following parameter macros in the string
which is used for the registration of command macros and for executing command.
But,
you cannot use them in the functions,
the input file for
source
command,
and the initial configuration file,
then you should use
evalmacro
command when you want to use any parameter macro in them.
- %C
-
The filename on the cursor position.
Or, it indicates the archive filename,
in the macro to register the archiver command.
- %X
-
The filename except its extension on the cursor position.
Or, it indicates the archive filename except its extension,
in the macro to register the archiver command.
Only the last one extension is removed.
T,
TA,
M
trailing
%X
are replaced by
%T,
%TA,
%M
except its extension respectively.
On MS-DOS version,
you can describe a trailing
S
as well as them.
- %P
-
The pathname of the current directory.
- %K
-
Prompt and return to
fd
after a command is finished.
But,
the meaning of
%K
is reverse in
EXECUTE_FILE
and
EXECUTE_SH;
it prompts by default and doesn't prompt if
%K
is specified.
You can never specify to prompt
in macros to register the archive browser of the launcher
and macros to register the archiver command.
- %T
-
List marked files separated by spaces as possible.
When files are so many that the command line length exceeds the OS limitation,
the rest of marked files are ignored.
- %TA
-
List marked files as well as
%T,
and repeat the same command for spilt files to complete all marked files.
- %M
-
Execute the same command as many times as marked files,
sending the marked file one by one.
It is useful to mark files by
MARK_FIND
and execute "mv %M %XM.bak" by
EXECUTE_SH.
- %N
-
Restrain the filename addition even if the parameter is omitted.
- %R
-
Make you input the additional parameter in executing a macro,
if the length of command string has enough margin.
The cursor position in input is placed on the position of
%R
in a macro.
But,
%R
is ignored in macros to register the archive browser of the launcher,
macros to register the archiver command,
and
EXECUTE_FILE,
EXECUTE_SH.
- %S
-
The 8+3 formed filename
with which the LFN formed filename on the cursor position is replaced.
You can use it
when you use external commands which can treat only 8+3 formed arguments.
T,
TA,
M
trailing
%S
can be described as well as
%X.
(DOS)
- %JS
-
The Kanji code of the string enclosed by this macro
is converted into Shift JIS.
(UNIX)
- %JE
-
The Kanji code of the string enclosed by this macro
is converted into EUC-JP.
(UNIX)
- %J7
-
The Kanji code of the string enclosed by this macro
is converted into 7bit JIS.
(UNIX)
- %J8
-
The Kanji code of the string enclosed by this macro
is converted into 8bit JIS.
(UNIX)
- %JJ
-
The Kanji code of the string enclosed by this macro
is converted into ISO-2022-JP.
(UNIX)
- %JH
-
The Kanji code of the string enclosed by this macro
is converted into HEX.
(UNIX)
- %JC
-
The Kanji code of the string enclosed by this macro
is converted into CAP.
(UNIX)
- %JU
-
The Kanji code of the string enclosed by this macro
is converted into UTF-8.
(UNIX)
- %JM
-
The Kanji code of the string enclosed by this macro
is converted into UTF-8 for Mac OS X.
(UNIX)
- %JI
-
The Kanji code of the string enclosed by this macro
is converted into UTF-8 for iconv,
which is used on environments using iconv-based UTF-8 such as Linux.
(UNIX)
- %JA
-
The Kanji code of the string enclosed by this macro
is converted into the Kanji code
which is used in the pathname indicated by the string.
The variables
SJISPATH,
EUCPATH,
etc. can specify what kanji code is used in each pathname.
(UNIX)
When no filename parameter,
such as
%C
and
%T,
is taken with the result to expand parameter macros in a command macro,
the filename on the cursor position is automatically added
to the last of expanded string,
as
./filename
form.
This addition is not done,
in case of the input string for executing command,
or when
%N
macro is specified.
Customize
You can customize
fd
as the following ways.
If you specify some configuration in multiple ways overlapped,
it is prior in this order.
-
- Executing builtin commands with EXECUTE_SH
-
You can execute builtin commands for each registration for
the internal variable definition,
the environment variable definition,
the alias definition,
the function definition,
the key binding,
the keymap changing,
the launcher registration,
the archiver command registration,
and the floppy drive registration.
- Customizer
-
EDIT_CONFIG
command is available for
the internal variable definition,
the key binding,
the keymap changing,
the launcher registration,
the archiver command registration,
and the floppy drive registration.
- Command line options
-
You can specify the command line options as
`-NAME=value'
form,
to define the internal variables.
- .fd2rc
-
You can prepare the initial configuration file
.fd2rc
on your home directory,
to execute the command which is written in this file,
before the startup of
fd.
You can describe builtin commands and external commands in it
to set up each configuration.
Yet,
when
fdsh
is invoked as a login shell,
.fdshrc
is read instead of
.fd2rc.
The initial configuration file
/etc/fd2rc
which is prepared by a system administrator
is read preceding
.fd2rc
and
.fdshrc.
If this file exists,
the initial configurations prepared by a system administrator are valid
unless you intentionally delete them in
.fd2rc
and
.fdshrc.
(On MS-DOS version,
these filenames are
$HOME\fd2.rc, $HOME\fdsh.rc
and
~FD\fd2rc.)
- Environment variables
-
Any valid variable name as the internal variable
can be valid to be defined as the environment variable in advance.
But the internal variable is always prior to the environment variable in
fd.
When the same named environment variable is used in another application,
you can also use the name which
FD_
is prefixed to each environment variable for
fd
only.
This environment variable with
FD_
is always prior to the environment variable without it,
then the definition of the environment variable with
FD_
is prior to the definition of the internal variable without
FD_.
Customizer
EDIT_CONFIG
command invokes the customizer to set up configurations interactively.
You can select the category with the right/left cursor key,
and select the item with the up/down cursor key,
and change its content with
[
Return].
When you finish to change,
exit from the customizer with
[
Esc].
The following categories are prepared.
-
- Variables
-
Change the value of internal variables.
The input method is different with the variable,
then you should input following the guidance on screen.
- Key bind
-
Change the command bound to each key.
When you newly bind a command to the key with no binding,
you should select "NewEntry".
If you select "Delete bind",
the existent key binding is deleted.
- Key map
-
Change the key code mapping for each special key.
If you push
[Esc]
when you are prompted to push the key,
the existent key mapping is deleted.
(UNIX)
- Launcher
-
Change the launcher registration for each extension.
When you newly register a launcher for the extension with no registration,
you should select "NewEntry".
If you input a null line when you input a command for the launcher,
the existent launcher registration is deleted.
- Archiver
-
Change the archiver command registration for each extension.
When you newly register a archiver command
for the extension with no registration,
you should select "NewEntry".
If you input a null line both when you input a command for pack/unpack,
the existent archiver command registration is deleted.
- DOS drive
-
Change the floppy drive registration.
When you newly register a floppy drive
for the drive name with no registration,
you should select "NewEntry".
If you input a null line when you input a device name,
the existent floppy drive registration is deleted.
(UNIX)
- Save
-
Save the configurations changed with the customizer into a file,
or cancel configurations to restore to the previous state.
-
- Cancel
-
Cancel the changed configurations within the specified categories,
and restore to the state before the customizer is invoked.
- Clear
-
Cancel all the configurations within the specified categories,
and restore to the default state.
- Load
-
Load configurations from the specified file.
- Save
-
Save all the configurations within the specified categories
to the specified file.
- Overwrite
-
Overwrite all the configurations within the specified categories
to the specified existent file.
The original configurations which has existed in the file are parsed,
and the configuration for the same target is overwritten at the same place
as possible.
The configurations which are not set up at present
and the configurations which are not supported by the customizer
are remains as it is.
When you specify the range of categories,
all categories are selected by default,
then you should turn on/off each selection with
[Space]
and decide with
[Return].
If you try to exit from the customizer without saving
after changing any configuration,
you will be confirmed whether if it is right to exit without saving.
While the changed configurations themselves are valid
even if you exit without saving,
when you want them to be valid in the next invoked
fd,
you must save them into the initial configuration file.
ENVIRONMENT VARIABLES
The following environment variables are valid in
fd.
These environment variables can be valid
if they are defined as the internal variables.
You can specify them as the command line options in
`
-NAME
=value'
form.

0
and null effects valid.
- SORTTYPE
-
The file list in the browser screen is not sorted by default,
but placed in order registered in the directory.
This variable specify it to be sorted by default.
The following are specifiable values.
-
0 not sort
1 by filename 9 by filename(reverse)
2 by extension 10 by extension(reverse)
3 by size 11 by size(reverse)
4 by timestamp 12 by timestamp(reverse)
5 by length 13 by length(reverse)
100-113 keep the last sorted type
200-213 keep it also in archive browser
-
If you specify the value of 100-113,
it is sorted according to the value indicated by lower 2 digits
just after invoked,
the last specified sorted type is kept when moving directory.
If you specify the value of 200-213,
the last sort type will be kept also after invoking the archive browser.
- TERM*
-
Specity the terminal name.
When this value is
dumb,
unknown
or
un,
it is regarded as the dumb terminal
to suppress any escape sequences in the internal shell
in spite of
DUMBSHELL.
If this value does not exist in
termcap(5)
and
terminfo(5)
entry,
it is executable only when it is invoked as
fdsh.
The terminal name will be variable dynamically,
then you can re-specify the suitable one as this value after invoked
for some strange terminal display and key input.
- THRUARGS
-
Pass through the pathnames as is,
which is specified as the startup arguments.
Fd
expands the meta character such as
~
and
${#}
in the given pathname by itself,
because the obsolete low-level shell cannot support these expansion extended by POSIX.
Fd
can sometimes expand the pathname given by the shell into the unexpected string
as a result of duplicate expansion,
because the latest high-level shell generally support these expansion.
This variable will be suppress the expansion of arguments.
Any value except
0
and null effects valid.
- TMPDIR
-
Specify the working directory
where the archiver command temporarily unpack files in the archive file.
The default value is
/tmp.
(On MS-DOS version,
The default value is
`.'.)
- TMPUMASK
-
Specify the file creation mask with octal expression for files and directories created temporarily in
TMPDIR.
But the mask value set by
umask
the builtin command is prior,
then actual mask value is the logical OR of this value and
umask
value.
- TRADLAYOUT
-
Use the traditional screen layout based on the original "FD".
In this layout,
the file size information will be always displayed,
whether
SIZEINFO
is set or not.
When the screen width is less than
80
columns,
this specification is invalid.
Any value except
0
and null effects valid.
- UNICODEBUFFER
-
Hold the UNICODE translation table on memory.
It will be fast to access the floppy drive and to translate from/to UTF-8.
You should set this if you have enough memory.
Any value except
0
and null effects valid.
- URLDRIVE
-
Validate the function of the URL drive.
Any value except
0
and null effects valid.
(UNIX)
- URLKCODE
-
Specify the Kanji code for filename on the host with the URL drive.
JIS8,
JUNET,
HEX,
CAP,
etc. among them are the Kanji codes used in Samba.
(UNIX)
-
SJIS, sjis Shift JIS
EUC, euc EUC-JP
JIS, jis 7bit JIS
JIS8, jis8 8bit JIS
JUNET, junet ISO-2022-JP
OJIS, ojis 7bit JIS (JIS C6226-1978 + roman)
OJIS8, ojis8 8bit JIS (JIS C6226-1978 + roman)
OJUNET, ojunet ISO-2022-JP (JIS C6226-1978 + roman)
HEX, hex HEX
CAP, cap CAP
UTF8, utf8 UTF-8
UTF8-mac, mac UTF-8 for Mac OS X
UTF8-iconv UTF-8 for iconv
default no convert
- URLOPTIONS
-
Specify communication options,
when the URL drive communicates with the host.
You can select individually whether if PASV, PORT, MDTM, FEAT each commands for the FTP communication are limited or not,
or whether if the exact file information is need or not.
On the HTTP protocol,
you will get the timestamp and size of files with some rounding error in bulk.
If you need the exact information,
the operations by file will spend the more communication time.
The default value is
0.
The following are specifiable values.
(UNIX)
-
0 standard
1 PASV
2 PORT
3 PASV & PORT
4 MDTM
5 PASV & MDTM
6 PORT & MDTM
7 PASV & PORT & MDTM
8 FEAT

27 PASV & PORT & FEAT & HTTP
28 MDTM & FEAT & HTTP
29 PASV & MDTM & FEAT & HTTP
30 PORT & MDTM & FEAT & HTTP
31 PASV & PORT & MDTM & FEAT & HTTP
- URLTIMEOUT
-
Specify the timeout in seconds,
when the URL drive communicates with the host.
If the communication from the host is lost for the time specified,
the communication is regarded as invalid and its connection will be shutdown forcedly.
If this value is
0
second,
the timeout operation is invalid to continue waiting response forever.
The default value is
0
second.
(UNIX)
- USEGETCURSOR
-
Use the VT100 compatible escape sequence getting the cursor position
in order to get the terminal size.
When the screen size of
fd
doesn't correspond with the terminal size,
this variable can be sometimes valid.
On some terminals
which don't support the escape sequence getting the cursor position,
the operation may be stopped.
In this case,
it is continued by inputting 'R' from the keyboard.
Any value except
0
and null effects valid.
(UNIX)
- USESYSLOG
-
Send the log to
syslogd(8)
the system logger with the level spacified by
LOGLEVEL
or
ROOTLOGLEVEL.
The log priority is LOG_ERR only some errors are caused,
otherwise the log priority is always LOG_INFO.
LOG_USER is used as the facirity if it can be specified.
Any value except
0
and null effects valid.
(UNIX)
- WIDEDIGIT
-
Widen the displayed digits for the number of pages and files.
The standard displayed digits for the number of pages and files are
2
and
4
respectively.
This expands them into
4
and
5
respectively.
Any value except
0
and null effects valid.
- WRITEFS
-
Forbid use of
WRITE_DIR
command.
If the value is
1,
the directory is written only when the command is executed intentionally,
and you are not confirmed after arranging the file order.
If the value is
2,
even writing by the command is invalid,
the directory writing is quite forbidden.

- UTF8ICONVPATH
-
- NOCONVPATH
-
Specify the Kanji code for filename per directory,
which is prior to
FNAMEKCODE.
You can specify multiple pathnames separating with
':'.
You are enough to specify only the top directory
where you want to use the Kanji code,
then you can use the Kanji code
in all of the directories under that directory.
In the directory which is described in
NOCONVPATH,
no Kanji code is converted ignoring the value of
FNAMEKCODE.
No pathname is specified by default.
(UNIX)
MULTI LANGUAGE SUPPORT
Fd
processes the Kanji character-set to input/output
as "EUC-JP" or "Shift JIS" according to setting in compile.
The the pathname including Kanji is displayed
in consideration for the 2nd byte character in Kanji.
You can dynamically select Kanji code to input/output
with
LANGUAGE,
INPUTKCODE
and
FNAMEKCODE
the internal variable.
You can input Japanese string with the Kana-Kanji IME mode.
You can use Kanji in the command macro and the command string,
but cannot use Kanji as the value of the internal variables.
You cannot use the multibyte symbol character as the meta character,
such as
'%'
and '"' and so on,
Kanji character is not counted as 1 character in the wildcard search.
And when you give the non-standard Kanji code for the OS to the shell
with the parameter macro such as
%JJ,
some Kanji is converted into the code including the meta character
such as
'$'
and
'\'
and so on,
to cause unexpected behavior.
In that case,
you can probably avoid it by quoting the string to be converted with
%'.

LIMITATIONS
Some terminals cannot send the input of certain function keys and special keys.
The sequence compatible with
VT200
is assigned as the default sequence which is not registered in
termcap(5),
and when the terminal cannot support this,
the key receipt or the screen control
due to be brought by this is not available.

When files in an archive file are packed with a pathname including "..",
the archive browser cannot work normally.
