✔️ minishell

This project is aim to understand how shell called bash works and this project is a part methodology learning students from 42 school (21 school in Moscow).

Implementation rests on AST(Abstract syntax tree)

Example input ./minishell command1 > file1 | file2 < command2

Example tree:

Available options

Minishell runs executables from an absolute, relative or environment PATH (/bin/ls or ls), including arguments or options. ' and " work the same as bash, except for multiline commands.

You can use redirections > >> < and pipes | as well as heredoc <<.

Environment variables are handled, like $HOME, including the return code $?.

Finally, you can use Ctrl-C to interrupt and Ctrl-\ to quit a program, as well as Ctrl-D to throw an EOF, same as in bash.

A few of the functions are "built-in", meaning we don't call the executable, we re-coded them directly. It's the case for echo, pwd, cd, env, export, unset and exit.

Usage

Using make will create the minishell executable.

Simply run it with :

./minishell
