42Minishell

A bash-like self-coded shell that works just like a regular shell:

• Displays a prompt while waiting for a new input
• Has a history of commands ran
• Searches and launches the right executable (relative or absolute paths)
• Interprets closed single (') and double (") quotes
• Interprets redirections (< , > , << and >>)
• Interprets pipes (|)
• Handles environment variables ($)
• Expands $? to the exit status of most recently executed pipeline
• Handles signals (ctrl-C, ctrl-D and ctrl-\) like in bash
• Implements the following builtins:
  • echo (with -n)
  • cd (absolute or relative path)
  • pwd (no options)
  • export (no options)
  • unset (no options)
  • env (no options or arguments)
  • exit (no options)

Compilation

Requires readline to be installed. git clone project to desired directory. Run make inside that directory. Run executable ./minishell.
