Creating a shell.... howto?

Best way to write your own shell is to look at current shell and try to implement something like that.
When you type some command on shell it will create new process for executing that command, use the same approach

Your code should do the following things first.
- listen in while loop for user commands.
- once user enters the command, create the new process by system call 'fork'.
inside child process execute the command entered by user using 'exec' system
call
- Try to use 'system' system call, so that you can avoid extra work.

I don't think that this code will take more than 300 lines.

Thank you for your pointers, much appreciated. Please could you also point me to some online documentation which will help me in making the shell. Thanx.
