Custom POSIX-compliant shell built in cpp20, based on "Build Your Own Shell" Challenge.

In this challenge, you build your own POSIX compliant shell that's capable of interpreting shell commands, running external programs and builtin commands like cd, pwd, echo and more. Along the way, you'll learn about shell command parsing, REPLs, builtin commands, and more.
