Scripts are files that contain shell commands which may be short or can be very complex. Scripts just make it easier because you can invoke one command to run all of the commands in the script. Here instead of using 8 separate commands you can use one command to execute all of them. This course is in a series of mini-courses to help you with Bash Shell Scripting. It is divided into several sections as you can see below. In addition, to help you in the challenge of learning bash shell scripting you will find a quiz at the end of each mini-course.
