To be able to describe the Unix process and write a program using the Unix process API. Practice utilizing signals, signal handling, and I/O redirection.
I under estimated how much I would learn from completing this project. While understanding the Unix process, signal, and signal handling were vital for completion, I found great value in many of the other functions required to succeed with this project. Specifically, expanding variables and manually exiting the shell. Writing the functionality for both of these procedures were reminders of how much we take for granted when using libraries and packags. Overall, this program was great for emphasizing the need to understand how programs function under the hood to better improve overall functionality.
Please feel free to run by using the included Makefile and test by placing p3testscript in the same directory as the shell program and running via ./p3testscript 2>&1. Any feedback is welcomed and greatly appreciated.
