I’m doing a (free) operating system (just a hobby, won’t be big and professional like gnu).

Here is a echo implementation, and a shell called mdsh (MaoutDuxSHell). A kernel should follow.

Building

$ make

Usage

1. run mdsh
2. test some commands like: $ echo aa bbb cc (this is the only available one for the moment)

echo will output every token passed as argument to the standard output. Each token will be separated by a space, and a newline will be insterted at the end.
