# minishell (@42Paris)
"As beautiful as a shell"
## About
Minishell is a project of the mandatory part of the cursus that I made with my friend [Corentin Debraix][1].
It's only made in C and the main goal was to create a shell working like bash.
In this case we had to understand how processes, redirections, pipes, execve and bash builtins work.
We also had to learn how bash was handling a command line (lexer / parser / exec).
- Here is the [subject][2]
`This project was code for MACOS`
