As beautiful as a shell

🧐 Description:

A miniature clone of bash.

🎲 Features:

• minishell can run executables from an absolute /bin/ls, relative ../../../../../bin/ls, or environment PATH ls with arguments.
• Environment variables are also handled including the return code $?.
• You can use redirections > >> < << and pipes |.
• Builtins: cd, pwd, echo, export, unset, env, exit.
• Single and double quotes work just like in bash, but not for multiline commands.
• Three signals are also handled just like in bash:
  • Ctrl-C interrupts a running process or brings up a new prompt.
  • Ctrl-\ quits from a running program and does nothing on the prompt.
  • Ctrl-D throws an EOF or exits minishell.

🔧 Usage:

1. Go into the root directory and run make.

cd minishell
make

2. Run the executable created in the output folder.

cd output
./minishell

✅ Credit

minishell was a two person project done with yabdelgh

I was responsible for reading input, the lexer, parser, environment variables, signal handling and command history.

While yabdelgh took care of command execution, pipes, redirections and signal handling inside child processes.
