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.

NAME

       logindevperm, fbtab - login-based device permissions

SYNOPSIS

       /etc/logindevperm

DESCRIPTION

       The  /etc/logindevperm  file  contains  information  that is used by login(1) and ttymon(1M) to change the owner, group, and permissions of
       devices upon logging into or out of a console device. By default, this file contains lines for the keyboard, mouse, audio, and frame buffer
       devices.

       The owner of the devices listed in /etc/logindevperm is set to the owner of the console by login(1). The group of the devices is set to the
       owner's group specified in /etc/passwd. The permissions are set as specified in /etc/logindevperm.

       Fields are separated by TAB and/or SPACE characters. Blank lines and comments can appear anywhere in the file; comments start with a  hash-
       mark, ` # ', and continue to the end of the line.

       The first field specifies the name of a console device (for example, /dev/console). The second field specifies the permissions to which the
       devices in the device_list field (third field) will be set.  These permissions must be expressed in octal format.  For  example,  O774.	 A
       device_list  is	a  colon-separated list of device names.  Note that a device name must be a /dev link.	A device entry that is a directory
       name and ends with "/*" specifies all entries in the directory (except "." and ".."). For example, "/dev/fbs/*" specifies all frame  buffer
       devices.

       Once the devices are owned by the user, their permissions and ownership can be changed using chmod(1) and chown(1), as with any other user-
       owned file.

       Upon logout the owner and group of these devices will be reset by ttymon(1M) to owner root and root's group  as	specified  in  /etc/passwd
       (typically other). The permissions are set as specified in the /etc/logindevperm file.

FILES

       /etc/passwd     File that contains user group information.

SEE ALSO

       chmod(1), chown(1), login(1), ttymon(1M), passwd(4)

NOTES

       /etc/logindevperm provides a superset of the functionality provided by /etc/fbtab in SunOS 4.x releases.
