scrot is a command-line utility for taking screenshots on Unix-like systems such as Ubuntu.
scrot was first released in 2000 and the latest stable release was in 2003 with no development since that time. However scrot still works perfectly well on a modern Ubuntu system.
Features include:
- Takes a full screen snapshot in user-defined quality PNG file
- Takes partial screen size: either selected by drawing with mouse or selecting a window
- Outputs screenshot directly to an image manipulating application such as GIMP
- Sets a delay and/or countdown on the screenshot
- Gets screenshots over a network on a remote computer
