1. Bash Scripting Basics

To give you a taste of what's to come, let's quickly review some Bash scripting basics:

• Bash scripts are plain text files that contain a sequence of commands.

• Scripts typically have a .sh file extension.

• To create an executable script, add the shebang (#!/bin/bash) as the first line of the file, followed by your commands.

• To make the script executable, use the chmod command: chmod +x script.sh

• To execute the script, use the ./script.sh command.

Here's an example of a simple Bash script:

bashCopy code#!/bin/bash

echo "Hello, World!"
