LSH is a simple implementation of a shell in C. It demonstrates the basics of how a shell works. That is: read, parse, fork, exec, and wait. So I think it's pretty cool. Since it's a simple implementation, it has some limitations.

• Commands must be on a single line.
• Arguments must be separated by whitespace.
• No quoting arguments or escaping whitespace.
• No piping or redirection.
• Only builtins are: cd, help, exit.
