What is Cmder Cmder is a commander console for Windows. The opening line on Cmder’s website explains it all. Cmder is a software package created out of pure frustration over the absence of nice console emulators on Windows. It is based on amazing software, and spiced up with the Monokai color scheme and a custom prompt layout, looking sexy from the start. All the magic of Cmder happens through use of ConEmu - a console program for windows and Clink which gives it a powerful bash style command line editing, completion, history and much more.
