I really dig this, but if I issue a command like cd, the output should only be showed to the person who issued the command.

but this is really fun! nice job!

What if you want to just say one of the commands? IMO, there should be some sort of prefix (like '/') before commands to disambiguate.

any prefix would make a command not a command, kinda like how people on twitter add a random character before a tweet starting with a user mention
