Add the "&" as I put above. What is happening is the cron job itself is
hanging around until adjkerntz exits. Telling it to execute in the
background (via the '&') allows the shell script to complete, thus
making the two (not really) zombie tasks also go away.
You could also use the -c option to grep, like this:
#!/bin/csh -f
if ( "`/bin/ps -ax | /usr/bin/grep -c [a]djkerntz`" == "0") then
/sbin/adjkerntz -i &
endif
I personally like the count option better, but everyone has his/her own
quirks...
