I know how to take a screenshot on my Ubuntu, but I want to take many screenshots within a limited time (taking screenshots of a single execution of a program which I can not pause).
Is there a program that takes the "PrtScr" keyboard key in charge and just stores every screenshot without asking? The standard Ubuntu tool pops up a dialog to ask where I want to save the file, I would like a tool that doesn't ask and just saves on the Desktop or wherever as 00001.png 00002.png etc.
