Invoke mysql_setpermission like this:
shell> mysql_setpermission [options]
options should be either --help to display the help message, or options that indicate how to connect to the MySQL server. The account used when you connect determines which permissions you have when attempting to modify existing permissions in the grant tables.
mysql_setpermissions also reads options from the [client] and [perl] groups in the .my.cnf file in your home directory, if the file exists.
mysql_setpermission supports the following options:
Display a help message and exit.
Connect to the MySQL server on the given host.
The password to use when connecting to the server. Note that the password value is not optional for this option, unlike for other MySQL programs.
Specifying a password on the command line should be considered insecure. See Section 18.104.22.168, "End-User Guidelines for Password Security". You can use an option file to avoid giving the password on the command line.
The TCP/IP port number to use for the connection.
For connections to localhost, the Unix socket file to use.
The MySQL user name to use when connecting to the server.
