Design and Implement a simple shell. The shell should

1. Parse the command line for a single command and all its arguments
2. Create and execute a process for the command (and its arguments) on the command line.
3. Graduate students will need to support input/output redirection.

Here's some code to help you.

• Code to show you how to fork and exec a child process
• Code to show you how to use fork, exec, pipe and dup2
• An executable shell

1. The Makefile I used for this assignment.
2. Note that I have 3 .h files and 3 .c files, you may use this organization of your code files. You may also come up with and use your own. You cannot put all your code in one file.
3. Here is my main.c

• Learn about the system call interface for process creation and execution.
• Learn about makefiles and software organization
• Learn to find and read man pages

1. Source code files
2. a readme, and
3. a Makefile to make your executable.

Good Luck!
