Hello all
I'm new in Unix, i'd like to write my own simple shell. It presents a command prompt and accepts and performs simple commands. Commands should be performed by child processes, created by use of fork(). The execvp() call should then be used to replace the child process image with the image of the desired UNIX command.It should accept at the prompt a UNIX command. It then performs the command, and then present a new prompt to the user. Command use should be restricted to the format
command [-option] [argument]
Thank you very much
