what's the shell command for dash screenshot application?

Question

I know in ubuntu, I can use Screenshot application using which I can take a screen shot for selected window. This means there is the application already on ubuntu. What's the command line command for that application? (I know gnome-screenshot lets us take the whole screenshot, but I want to select a region when taking the shot.)

In order to grab a screenshot of window, use this command
gnome-screenshot -w

In order to grab an area, use this command
gnome-screenshot -a

   -c, --clipboard
