PMSS (Poor Man's Screenshooter) is a command line utility which makes capturing screenshots a piece of cake. It is a small, freeware, easy to use shell script which hardly consumes any system resources. It uses well know Linux command line utility, Scrot , on the backend. In order to understand the effectivity of PMSS, lets first understand how Scrot works. Scrot is an open source tool which is already included in the repositories of all popular Linux Package Managers, however taking screenshots using this tool requires you to specify multiple command line parameters. Scrot is a great tool but it is not very user friendly. The creators of PMSS have used the functionality of Scrot along-with a new but extremely easy to use command line interface. PMSS also requires another command line tool called xdotool (A utility to stimulate keyboard inputs or mouse movements). You can do alot of stuff with PMSS, you can:
- Capture the screenshot of your system's entire screen.
- Screenshot the particular window in focus.
- Capture the screenshot of the specific area of the screen selected via mouse.
- Easily upload your captured screenshots to imgur.
- Get the image upload links in various formats.
- Review the logs of the upload operations performed by this utility.
- Easily empty your screenshot directory by using a single keystroke.
In this article, we will discuss its installation and usage process on modern day Linux operating systems, Ubuntu 16 and CentOS 7, please be advised that same set of instructions will work for any older versions of these Linux flavors, too. Ready ? Great, lets get started on setting it up on Linux system.
