In this post I intend to show how easy it is to take a screenshot from the CommandLine.
Why would you want to do that?
Well there are times when you simply want to take a screenshot of the screen at certain times to track your activity. Or to make a simple screencast without having to install additional tools.
FFMPEG can be downloaded and installed from the following website: https://www.ffmpeg.org/
For Linux you can also install it via the commandline
To install libav:
apt-get install libav-tools
To install ffmpeg:
apt-get install ffmpeg
To take a screenshot on Linux just type the following in your terminal
ffmpeg -f gdigrab -i desktop -vframes 1 screenshot.jpeg
Take a screenshot on Windows
ffmpeg -f x11grab -video_size $(xdpyinfo | grep dimensions | cut -d" " -f7) -i $DISPLAY -vframes 1 screenshot.jpg
