Command finished notification with Ruby

I wanted a visual notification in Ubuntu when long running commands finished in Terminal. My solution, run the command and pipe it into notify.

$ a-long-running-command | notify


#!/usr/bin/env ruby
require 'rubygems'
require 'libnotify' :summary => "Command finished.", :body => "#{}"

Make it executable

chmod u+x ~/scripts/notify.rb

add an alias to it in ~/.bashrc

alias notify="~/scripts/notify.rb"

, rubygems, and libnotify.

Similar solutions:
“alert” alias (I’ll be switching to this in Maverick),
a python version
