Hi,
How to take the screenshot of the screen through terminal by providing co-ordinates(x,y,hight,width), normaly we get screenshot of full screen but I need only, half of the screen.
Please help out.

Thanks and regards

After a bit of googling I found this:

use scrot to get the image:

Then use mogrify to crop them to be the right size:
