Well, Hellmaster...

Are you wanting to create your own C versions of "cat", "more", "head", and "tail"? Or are you
referring to the shell environment itself? As in, are you wanting to create your own command
based application that runs applications within your own host environment?

Or are you saying that you want to create your own scripting language similar to BASH?

No, not that. I want to writing a C program that similar there command to perform their funtions in Linux environment
