Unix Processes

Let us change our focus from the way UNIX handles files and devices to the way UNIX handles running programs, also known as processes. By the end of this module, you will be able to:
  1. Define what a process is
  2. Identify the various types of processes you may encounter on a UNIX system
  3. Know the basic process attributes and their role in access control
  4. Understand how new processes come into being
  5. Determine related families of processes
  6. Create, schedule, and run a periodic process

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.
