processes. By the end of this module, you will be able to:

How does Unix run Programs?
To execute a program, you only need to type its name. You may need to type ./ before the name.
Ctrl c - This command will cancel a program that is running or will not automatically quit.
It will return you to the command line after execution so you can run additional programs.
