Bash Script


Introduction to Bash Scripting

Bash scripts are files containing commands that you run in the terminal. They automate tasks and make your work more efficient.


Creating a Bash Script

To create a script, start with the shebang #! followed by the path to Bash, usually /bin/bash. Make sure your script has execute permissions.

Example: Simple Bash Script

#!/bin/bash
# This script prints a greeting message
echo "Hello, World!"

Using Variables in Scripts

Variables store data that your script can use. Assign values using the = sign without spaces.

Example: Using Variables

#!/bin/bash
# Assign a value to a variable
name="World"
echo "Hello, $name!"
