I recently wrote a "how to take a screenshot in Linux tutorial", and I included a shell script that helped take screenshots in GNOME with a custom application launcher on the taskbar.

This page originally had 7 ways to take a screenshot in Linux. It keeps growing and now there are more than 7. If you know of other useful ways to take a screenshot in Linux, leave a comment below...

There are several ways to take a screenshot Linux in general. I'm going to use Ubuntu as an example, but most of these will work on any Linux distro. If you aren't using GNOME, then the GNOME-specific items won't work.

I'll start with the common ways to take screenshots in Linux, and then show you a nice shell script for taking custom screenshots in GNOME with just one click of the mouse. The shell script will also work in other windows managers like KDE, but you will have to figure out how to make the custom application launcher for it.
