Simple Shell in C!

Project was a learning experience into how to run basic processes though replicating a bash shell in c
Runs on Linux systems

Implemented functions:

• Runs basic commands from bash: cd, ls, pwd, etc.
• exit command exits from the shell, killing all background processes
• & at the end of a command will send it to run in the background, prinitng a message when it completes
• Ctrl + C interupts the current or any parallel (&&&) running processes in the foregorund
  • (Like regular bash shell)

&& function - Sequential

Allows for input commands to run in sequence left to right when specified

• Example: echo hello && sleep 3 && echo hi

&&& function - Parallel

Allows for input commands to run in parallel (same time) when specified

• Example: echo hello &&& pwd &&& ls

Note:

&&, &&&, and & do not currently have implemented functionality to be ran at same time
Wouldn't exactly make sense to run both && and &&&, but implementing functionality for & into both might be

Future Improvemenets / Add-ons

• Implementing piping and redirection operators
• Possible periodic cleanup for zombie processes (like in regular bash)?
• Better handling of memory and cleanup
