minishell

This project is to create a simple shell. Concepts about processes and file descriptors are introduced.

This is a group project completed by T. Clement & J.B. Cornelisse

Technical considerations

The following elements need to work like in bash

Show a prompt when waiting for a new command
Search and launch the right executable (based on the $PATH variable or by using relative or absolute path)
Implement the below builtins:
- echo with option ’-n’
- cd with only a relative or absolute path
- pwd without any options
- export without any options
- unset without any options
- env without any options and any arguments
- exit without any options
Pipes |
' and " except for multiline commands
Redirections < > >> << except for file descriptor aggregation
Environment variables ($ followed by characters)
$? to store exit status of the previous command
ctrl-C, ctrl-D and ctrl-\

Run the following commands

$ git clone https://github.com/DelicaTessa/42-minishell
$ cd 42-minishell
$ make
$ ./minishell
