I am trying to write a script that will only run when I receive a hangup signal (i.e. when I am forcibly disconnected). How do I determine that I am indeed HUPped? So far, I have: #!/bin/sh #deathtrap -- will run these commands if I get HUPped trap hangupscript 0 When I run this interactively with: % nohup deathtrap & The script wants to run immediately. What am I doing wrong? What I really want to do is have my .logout run from tcsh in the event that I am lorcibly logged out. Currently, it only runs if I type "logout". HELP! ____ Mike O'Connor <mjo@ais.org>

Of course it does -- trap #0 means upon EOF, which occurs at the
end of the "deathtrap" shell script. Try trap #1, and make sure
the "deathtrap" script doesn't terminate except upon the trap.mjo@irie.ais.org (Mike O'Connor) (04/03/91)
