Bourne in AT&T Bell Labs in the mid-1970s. The Bourne Shell (sh) is the first kind of shell programmed by Stephen R. In UNIX, there are 2 main types of Shells.

The command prompt looks something like this: The Shell reads the command only once you press 'Enter'. The command prompt reads the first word and interprets the command. This command prompt is the interface, on which you can write and execute your commands and programs. The prompt, '$', is called the command prompt, which is displayed by the Shell. Each version supports its own set of commands and functions. There are different versions/flavors of Shell, just like different versions of Operating Systems. We run the commands, programs, and shell scripts directly on Shell. It wraps inside of the OS and protects it from any external damage directly. While the Shell receives the commands directly from the user and sends it to the kernel for processing and in turn, returns back the response to the user.

The kernel acts as a window for the software programs to recognize and run on the hardware components. The outermost shell of the Linux OS is Shell. The innermost core of the Linux OS is the kernel. The architecture of a Linux OS helps us understand the anatomy of Shell. In this Shell ScriptingTutorial, I will be discussing the following topics:

Gaining expertise in basic administrative commands on command-line Interface (CLI) will help you automate the routine tasks and will help you save more time, whether you are a system administrator, a developer, or a Linux enthusiast. Once you learn simple bash commands, you can easily learn Python and Perl, as you will be well aware of how Linux works and what it can do.

Scripting is increasingly gaining popularity in today’s world, spanning from the networking domain to supercomputers. Shell scripting allows you to utilize the powerful capabilities of the shell and automate a lot of sequential tasks, which otherwise would require a lot of commands. The Shell script is a computer program or an environment designed to be run by a UNIX-like Operating System, which can be easily understood and interpreted by the Unix kernel. Shell scripting is the method of instructing the shell to perform some functions through the shell script. This Shell scripting tutorial is aimed at covering all the basics and important information about scripting in Linux or Unix-like systems.
