relogin(ADM)

relogin -- rename login entry to show current layer

Syntax

/usr/lib/layersys/relogin [ -s ] [ line ]

Description

The relogin command changes the terminal line field of a user's utmp(F) entry to the name of the windowing terminal layer attached to standard input. write(C) messages sent to this user are directed to this layer. In addition, the who(C) command will show the user associated with this layer. The relogin command may only be invoked under layers(C).

relogin is invoked automatically by layers to set the utmp entry to the terminal line of the first layer created upon startup and to reset the utmp entry to the real line on termination. It may be invoked by a user to designate a different layer to receive write messages.

-s: Suppress error messages.
line: Specifies which utmp entry to change. The utmp file is searched for an entry with the specified line field. That field is changed to the line associated with the standard input. To learn what lines are associated with a given user, say jdoe, enter:

ps -f -u jdoe
and note the values shown in the ``TTY'' field (see ps(C)).

Exit values

Returns 0 upon successful completion, 1 otherwise.

Limitations

If line does not belong to the user issuing the relogin command, or if standard input is not associated with a terminal, relogin will fail.
