This project will allow you to delve into a UNIX mechanism in detail that you already know by utilizing it within your program.
This project is about recreating a simple command
< input "cmd" | "cmd" > output
You need to verify the input and output file and return the correct error code!
You can't open in (return normally one) but I create after out so return 0.
You can open in (return normally zero) but I can't open out so return 1.
You need to continu if you can't open out
You need to stop if you can't open in (chmod 777 out here)
Don't copy, but learn.
