If you use Windows Command Line, or Unix Shell / Terminal, and miss the GUI stuff, then here is a cute little utility application you may find very nice. It's called hotwire-shell. It nicely blends some of the GUI aspects and the power of the command line.
Basically you will have a text entry with auto-complete for commands, file-names, directory-names, full history, and a top Window for the output that is nicely formatted for various outputs, and includes built in search, so you can search through the pages of output.
You can do most of this stuff with the existing Windows Shell and some grep or more but this looks nicer.
It works on Linux and Windows.
