Shows all those processes; useful when building some massively forking script that could lead to zombies when you don't have your waitpid()'s done just right.

Add to your bash profile to minimize carpal tunnel syndrome. Doesn't work with [email protected] but appending "-l user" works fine if needed. Works for ping as well.. complete -W "$(echo `cat ~/.ssh/known_hosts | cut -f 1 -d ' ' | sed -e s/,.*//g | uniq | grep -v "\["`;)" ping
