Many of us use ‘Prnt Scrn’ key to capture snapshots for our day-to-day work. On Ubuntu there is a bug that disables this key when a drop down menu of a program is open. I too faced the same problem and looked around for a tool that might do the required job. After a bit of googling, I found that there exists a command line utility gnome-screenshot (for gnome environments) that can do most of the screen-shot capturing work smartly.
In this article, we will discuss how to use gnome-screenshot utility along with its options through some examples.
