@load "inplace" # Please set INPLACE_SUFFIX to make a backup copy. For example, you may # want to set INPLACE_SUFFIX to .bak on the command line or in a BEGIN rule. BEGINFILE { inplace_begin(FILENAME, INPLACE_SUFFIX) } ENDFILE { inplace_end(FILENAME, INPLACE_SUFFIX) }
By default, each named file on the command line is replaced with a new file of the same name whose contents are the results of running the AWK program. If the user supplies an AWK variable named INPLACE_SUFFIX in a BEGIN rule or on the command line, then the inplace extension concatenates that suffix onto the original filename and uses the result as a filename for renaming the original. # .SH NOTES # .SH BUGS
