Minishell for Linux
A compact POSIX-style shell with process creation, pipes, redirection, signal handling, and a built-in archive command.
The shell uses the POSIX process model to execute programs with fork and
exec, connect commands through pipes, redirect files, and handle interactive
signals. It also includes built-in commands, including a small archive
facility, rather than delegating every operation to another executable.
Building it made process groups, file descriptors, and the order in which a shell applies redirections much more concrete than using those features from a terminal.
