  bash, or any other shell. In a shell, you can set aliases, and even create intermediate functionality to interface with. You can even write software that works as a front end for your shell. The shell is so far removed from functionality, it hardly implements any at all. Instead, it uses entirely separate programs by providing the user a consistent and configurable interface to those programs.
