Hi, I want to know about how to write the following custom commands using c code: It is also worthy to be noticed that there must not be any use of system(), fork(), exec() commands: 1. cp copy a file 2. mv move a file 3. rm remove a file 4. cd ability to change directory 5. rmdir for removing directory So let me know how to write code in c language to emulate the above commands. I would be grateful for fast and reasonable help to get started on this work. Regards Murtaza
