We should begin with a few considerations on the Unix operating system. You should know it has been developed in the early 1970s at Bell Labs, being one of the first platforms that have been written in the C programming language. As a result, Unix could run on any computer equipped with a C compiler. This attribute combined with its low price led to its growing popularity, not only to universities, but also to commercial companies and to the United States government. Unix has been originally distributed in its source language format, thus making it possible for developers to customize it for their own needs. As a consequence, there have been various versions of Unix available at the end of the 1970s. After the AT&T break up in 1982 it was hard to define a standard version of Unix, and nowadays both the “Unix” trademark and the “Single UNIX Specification” interface are owned by The Open Group.

As you already should know, an operating system is the interface that connects the hardware components and the software running on them. Perhaps you wonder what a shell script is. It is the command interpreter of an operating system. The shell is often viewed as a programming language itself. Since timing is very important in today’s fast-paced and demanding world, it makes no sense wasting precious time for typing a widely used sequence of commands over and over again. It is particularly a waste of time when the respective sequence is very long or difficult. Scripting makes your life easier because it automates these command sequences, thus making your work easier and more efficient. Scripting makes the computer do the work for you. Unix uses shells to accept the commands typed by a user. A shell will run if you type its name and there are three shells that are most commonly used in Unix: the C shell, the Bourne shell and the Korn shell, which is highly programmable. Similar to other programming languages, the C shell language has variables. Some of them are useful for controlling the operation of the shell, while others can be created to manage the operation of a shell script file. All shells incorporate functions that enable the creation of shell scripts. To conclude, shell scripts are strings of shell commands and constructs meant to automate as much as possible in order to ease your mission as a Unix user.
