Sure, but given that I already use screen, what use cases would I find easier using job control instead of plain screen?

  Simple command line timer: remind() { [[ $# -ge 2 ]] || { echo >&2 "Usage: $FUNCNAME time msg"; return 1; } local sec="$(($1*60))" ( trap "echo \"\$sec seconds left\"" QUIT while ((--sec > 0)); do sleep 1; done say "${@:2}" # OS X only, replace with your favorite notifier ) 2>/dev/null & } $ remind 30 get the laundry Query time remaining with kill -QUIT %jobspec. Good for systems that don't have at(1).

    Thanks, that's useful! Favorite notifier: echo "${@:2}" | growlnotify -t Reminder -s -m -

    Hm. That looks like quite a typing exercise. What's wrong with: ( sleep 1800 ; say "get the laundry" )&

      His can be added to your .bashrc/.bash_profile, and then all you have to type is: remind [minutes] [message] Functions can be imported to your shell. =)
