Description
Like tools such as whiptail and dialog, Zenity allows easy creation of GUIs,[2] though it has fewer features than more complex GUI-creation tools.[3]
Other scripting languages such as Perl and Python can be used to construct full-scale GUI applications, but the zenity program enables a shell script to interact with a GUI user.... [The] user interface is not as refined as one that could be provided by a full-featured GUI application, but it is perfectly suitable for simple interactions.
— Chris Tyler[4]
Cross-platform compatibility
As of 2012[update], Zenity is available for Linux, BSD and Windows.[5] A Zenity port to Mac OS X is available in MacPorts and Homebrew.
As of 2018, Zenity ports for Windows are available: zenity-windows (based on version 3.20.0) and winzenity (based on 3.8.0 / statically linked)
Zenity does not possess any built-in scripting capabilities and it must, therefore, rely on an interpreter for processing. One option is Python in combination with the PyZenity library.[6]
