screenFetch is a small, but awesome utility that displays the logo of your distro in ASCII ART – with colors, as well some information about your environment. It supports a lot of Linux distributions and there respective logos, most main stream Desktop Managers and a lot of window managers. screenFetch can (and is it’s main purpose) take screenshots with the info on screen ! I think is just awesome and I love ASCII ART !
You can see what options it can take with screenFetch -h
