38.17 Automatically Kill Background Processes on Logout in csh

In many versions of the Bourne shell, background processes (1.26) are automatically killed with a HANGUP signal (signal 1) on logout. But the C shell makes background processes immune to signals and a HANGUP signal at logout doesn't affect the processes; they keep running.

If you want the C shell to work like the Bourne shell, put lines like these in your .logout file (3.1):

/tmp ! -z -v eval	set tf=/tmp/k$$ jobs >$tf if (! -z $tf) then # there are jobs jobs >$tf.1 # rerun it to dump `Done' jobs # skip Stopped jobs (killed by default) grep -v Stopped <$tf.1 >$tf; rm $tf.1 # cannot use a pipe here if (! -z $tf) then # there are running jobs eval `echo kill -1; sed 's/.\([0-9]*\).*/%\1/' <$tf` endif endif rm $tf

Warning: this may run afoul of various csh quirks (47.2). [To watch this work, put set verbose echo (8.17) at the top of your .logout file. If the logout process clears your screen or closes the window, you can give yourself n seconds to read the debugging output by adding sleep n (40.2) to the end of your .logout file. -JP ] The important trick is to run jobs >file, not jobs | command, as the latter runs jobs in a subshell (38.4) and thus produces no output, although jobs | any-csh-builtin is good for a laugh :-).
