NAME

relogin - rename login entry to show current layer

SYNOPSIS

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

DESCRIPTION

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

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, type ps -f -u jdoe and note the values shown in the TTY field [see ps(1)]).
