mybash

A basic command interpreter that executes bash commands. Written in C, using OS primitive calls like read, fork and exec.

Reads commands from stdin, parses them and their arguments and executes them in a new OS process.

Also has support for background mode. sleep 2 & sleeps for two seconds but lets you enter a new command immediately.
