I have a long list of cpanm jobs,
don’t want to put them in a batch all toghether,
and want to get signalled, when each of them is done:
$ while true; do beep; done
In my case the beep is acutally just the flashing of an xterm window.
Update:
Yes, notify-send is far, far, far superiour, growlnotify on OS X.
Thanks for the pointers!
