Unix Tip #4570- September 15, 2025
KILL X
Quick way to close your X login session (for SysV)
for PID in `ps -u$USER | grep "fv[wm]" | awk '{print $1}'`; do kill -9 $PID; done
Or throw it into a shell script:
--- cut here ---
#!/bin/sh
for PID in `ps -u$USER | grep "fv[wm]" | awk '{print $1}'`; do
kill -9 -$PID
done
--- cut here ---
(the [] conceal the grep from ps, which would mean it would
kill itself before doing anything useful. as written up,
it looks for fvwm's process, which is the window manager I
use; rewrite it as needed i.e. for Motif - mwm,
Open Look - olwm, etc.)
Write this up in a shell script contained in your $PATH
or alias it and you're cooking with gas.
