Linux Animated Gif
The program peek can be used to make animated gifs in Linux. You can record a screen area or the complete screen.
The screen recorder comes with an easy to use interface for X.
You put the Peek window over the area you want to record and click “Record”.
Peek is optimized for generating animated GIFs, but you can record to other formats like WebM or MP4 if you prefer.
Peek works on X11 and Wayland (GNOME Shell).
