MiniShell

Introduction:

• Minishell is the first group project we have to do at 42lausanne. This project makes you code a minimalistic shell following bash behaviour in C.

• As we can choose our teammate, the team will be composed of lray (@Ray-cmd) & mflury (@FizzYxWizzY).

Installation:

1. First, git clone the repository:
   • git clone https://github.com/Ray-cmd/minishell Minishell_42
2. Then, compile the project at the root of the repository:
   • make
3. Finally, launch the minishell:
   • ./minishell

How does it works:

• Minishell gives you a prompt while waiting for commands.

• It checks if all the passed arguments are valid and makes an abstract syntax tree out of them. categorizing them such as command, argument, file, redirection and pipe.

• Then it runs executables if it can find a valid path to them using the environement variable $PATH or by their path dirctly. (eg: ls and /bin/ls basically giving the same result)

• Otherwise, it looks if its a builtins, such as echo, cd, pwd, export, unset, env and exit.

• Minishell also have to manage some signals, such as Ctrl-C, Ctrl-D and Ctrl-\ that should reproduce bash behavior.

Particularities:

• The readline function has leaks that we dont have to correct for the project.
