What it is

A minimal Unix shell: the classic minishell exercise, kept small enough to read in one sitting. It reads a line, splits it on whitespace, fork()s, runs the command with execvp() in the child and waits for it in the parent. That is the whole mechanism every shell is built on.

What it doesn't do

One command at a time: no pipes, no redirection and no built-ins yet, so cd doesn't work. That keeps the core readable; each missing feature is the next exercise.
