Minishell

A small reproduction of a bash minishell capable of handling the most common shell operations and the most basic internal commands. For more: GitHub repo.

🐚 The shell should:

• 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) like in bash
• It must implement the builtins like in bash:
  • 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
• ; in the command should separate commands like in bash
• ' and " should work like in bash except for multiline commands
• Redirections >> should work like in bash except for file descriptor aggregation
• Pipes | should work like in bash
• Environment variables ($ followed by characters) should work like in bash
• $? should work like in bash
• ctrl-C, ctrl-D and ctrl-\ should have the same result as in bash
