TTYACTION(5)						      BSD File Formats Manual						      TTYACTION(5)

NAME

     ttyaction -- ttyaction file format

DESCRIPTION

     The ttyaction file specifies site-specific commands to run when a login session begins and ends. The ttyaction file contains a list of new-
     line separated records, where each record has the following three fields:

     ttyname   Name of the tty line(s) on which this line should apply.  The name is relative to the /dev directory, similar to how such devices
	       are named in the /etc/ttys file.

     action    Name of the action for which this line should apply.  The action names currently defined are "login", "getty", "telnetd" and
	       "rlogind" which indicate which program is processing this file.	(Note that "login" begins a login session, while the other three
	       are run after a login session ends.)

     command   What command to run if this record matches.

     The first two fields are delimited with blanks or tabs, and the command field is all text to the end of the line.	Either or both of first
     two fields may contain wildcard match patterns as implemented by the fnmatch() library function.

     All command strings are executed by passing them to /bin/sh -c running as "root," with an environment containing:

	   TTY=ttyname
	   ACT=action
	   USER=username
	   PATH=_PATH_STDPATH

     These variables may be used directly in the shell command part of the record for simple tasks such as changing the ownership of related
     devices.  For example:

	   console  *	   chown ${USER}:tty /dev/mouse

     will chown the mouse appropriately when the console owner changes.

EXAMPLES

     Here are some more example records:

	   tty0    login   /somewhere/tty_setup ${TTY}
	   tty0    getty   /somewhere/tty_clean ${TTY}
	   *	   *	   /somewhere/ttyfrob ${TTY} ${ACT}

HISTORY

     The ideas for the /etc/ttyaction file were inspired by the /etc/fbtab file under SunOS.
