Is there any way to do a console application for MenuetOS? I seem to remember a "simple linux emu" in an old version, and have heard about a "shell" of sorts. Does anyone have any pointers to these (it'd be nice if they had source I could review as well)?

Look here for the "cmd_0-27.7z" file (almost to bottom) You will need 7zip to uncompress it (at top)

There is a MHS bash emulator out (don't know were) but it is limited commands (cmd aswell I think)
