I need a C shell made to be used in Linux terminal which shows working directory, contents of the directory, etc. It should use child and parent processes, and read in text from user commands (so if a user does cd) they will be able to go back to the directory. It should also use system calls and have the child to run in the background while the parent processes run. Any help at all would be appreciated as I am extremely new to C in general, let alone making a custom shell from scratch. Thank you in advance.
