scrot (SCReenshot) is a simple command-line screen capture utility for X11. It can capture the entire screen, specific windows, or user-selected regions. Screenshots are saved as PNG, JPEG, or GIF files.
The tool supports delayed captures, thumbnails, and executing commands on the resulting image (useful for automatic uploading or editing). Special format strings allow dynamic filenames based on date, time, and dimensions.

X11 only; for Wayland use grim with slurp. Selection mode may not work with all window managers. Some compositors may cause issues with window captures.

Originally written by Tom Gilbert, who also created feh. A simple, focused screenshot tool that has been widely used in Linux desktop environments, often integrated with keyboard shortcuts for quick captures.
