The 42sh is an Epitech project that aims in creating a complete shell from scratch.
We only use Standard C Lib, we wrote it in 2 weeks, in a group of 4 students.
Launch program from $PATH, local executables.
You can use pipes, simple or double redirections.
Line-editing, auto-complete (file, $PATH executables), local history.
Wildcards *, config file (.42shrc).
cd, setenv, unsetenv, alias.
Just clone and cd 43sh, make, and launch with ./42sh.
You can launch the shell with ./42sh -c "some command" to exit after execution of the argument.
