Introduction

As Linux systems become larger and more complex, manually typing commands becomes inefficient, repetitive, and error-prone.

Shell scripting allows administrators and DevOps engineers to automate repetitive tasks by writing a sequence of commands into a text file that the shell executes automatically.

Shell scripting is one of the most fundamental automation skills in DevOps and serves as the foundation for many deployment, monitoring, provisioning, and maintenance tasks.

What is Shell Scripting?

A shell script is a plain text file containing Linux commands that are executed sequentially by a shell interpreter such as Bash (Bourne Again Shell).

Instead of typing commands one after another in the terminal, you write them once inside a script and execute the script whenever needed.

Think of it as creating your own command-line program.

Example:

#!/bin/bash

echo "Setup and configure server"

Why is Shell Scripting Important?

Shell scripting is one of the most valuable skills for Linux administrators and DevOps engineers because it allows automation.

Without scripting:

• Tasks must be repeated manually.
• Human error increases.
• Operations become slower.
• Large-scale infrastructure becomes difficult to manage.

With scripting:

• Servers can be configured automatically.
