a Very useful GNU/Linux command

convert input.png -transparent white output.png

What the above command does is that,

Suppose you have an image file with a background color (white in this case), the above command will delete that (white) layer and make the image transparent.

In my opinion, this is a very useful command especially for people who do not know how to use the GNU Image Manipulation Program to edit images.
