Two way bash process communication

This is a code example that allows you to have two way communication with a persistant bash process. I made this because the likes of popen and system only allow you to run one command with no variable persistance.

Pros:

• Allows declaring and reading of variables between different commands
• Easily read exit status and output of each command ran
• Can execute long running commands and will return when it has finished

Cons:

• More overhead than popen and system
