Description
An Operating System consists of many components, but its two main components are: Kernel and Shell.
What is Kernel?
Kernel; It enables communication between hardware and software. Kernel is the innermost part of an operating system. It is responsible for managing all of the system’s resources, such as the CPU, memory, and storage. The kernel also provides a set of system calls that allow user-mode programs to interact with the hardware.
What is Shell?
Shell is a program that lets you interact with your computer’s operating system. It takes the commands you type in and turns them into instructions that the operating system can understand.
What is Shell Script?
Shell Script is an open-source computer program designed to be run by the Unix/Linux shell program. Shell scripts allow us to write down a sequence of shell commands in a file and then execute them all at once. This can save us a lot of time and effort, especially if we need to run the same commands regularly.
With this course, we will see the basics of writing shell scripts in this command sequence. Now let’s take a look at the contents of Shell Scripting Essentials:
