Flameshot is an open-source command line-based screenshotting tool that lets you capture whole or specific screen areas and immediately make annotations before saving them locally or online to Imgur. If you choose to save the shots online the link is automatically copied to your clipboard for sharing.

Using Flameshot gives you access to freehand drawing, lines, arrows, circles, boxes, highlighting, blur, text, and pin annotation options.

You can customize Flameshot’s colour and size, and use of its on-screen buttons for quick tasks like Undo, Copy to clipboard, Save file, Upload to Imgur, Move screen selection.

How to Use Flameshot in Linux

Flameshot’s icon lives in the system tray when the app is running and you can right-click it to reveal menu items to open the configuration window and the information window. From here you can reveal all the keyboard shortcuts to use in the GUI capture mode.

The rest of Flameshot’s controls are only accessible via the CLI. Luckily, they are not difficult to remember.

Start a capture GUI mode and save to a custom path:

flameshot gui -p /path-to-captures

Open GUI with a 5-second delay:

flameshot gui -d 5000

Fullscreen capture with a custom save path (no GUI) and delay:

flameshot full -p /path-to-captures -d 5000

Fullscreen capture with custom save path copying to clipboard:

flameshot full -c -p ~/myStuff/captures

Capture the screen containing the mouse and print the image (bytes) in PNG format:

flameshot screen -r

Capture the screen number 1 and copy it to the clipboard:

flameshot screen -n 1 -c
