create a simple shell that imitates bash.

minishell

In the 42 project, we are redeveloping our own version of a compact bash. It's a program designed to interpret prompts and initiate executables with arguments, incorporating several built-in functionalities.

How to use it

Using make will create the minishell executable. Simply run it with :

make && ./minishell

Available options

Minishell can execute programs using either absolute paths, relative paths, or paths found in the environment (like /bin/ls or simply ls), and this includes passing arguments or options. Single (' ') and double quotes (" ") function identically to bash, except they do not support commands spread over multiple lines.

the shell supports using redirections (>, >>, <, <<) and pipes (|).

It also manages environment variables, such as $HOME, and captures the return status code $?.

Additionally, Minishell responds to Ctrl-C for interruption, Ctrl-\ for quitting a program, and Ctrl-D to input an EOF, all in the same manner as bash.

Several functionalities are "built-in", which means they are reimplemented within Minishell rather than invoking external executables. These include commands like echo, pwd, cd, env, export, unset, and exit.
