GNOME Command Line Dialog Utility
Zenity is a basic rewrite of gdialog, without the pain involved of trying to figure out commandline parsing. Zenity is zen-like; simple and easy to use. Zenity Dialogs: Calendar, Text Entry, Error, Informational, File Selection, List, Progress, Question, Text Information, and Warning. Zenity is especially useful in scripts.
