Processes and shells

This module covers basic information about how shell scripts are executed on a UNIX system. Subsequent modules in this course will focus on the programming aspects of the shell. Before we begin those modules, we’ll look at the difference between using the shell as an interactive command interpreter and using it as a programming language. We’ll also examine techniques available for running a shell script and go over what processes are started when you run the shell using the various techniques.
