Bash scripts are a powerful tool for automating repetitive tasks and simplifying complex workflows. If you’re new to programming, Bash scripting is an excellent place to start because it’s a user-friendly language that’s easy to learn. In this post, we’ll introduce you to the basics of Bash scripting and provide some examples to help you get started.

What is Bash scripting?

Bash is a command-line shell used in Unix-based operating systems like Linux and macOS. A shell is a program that interprets and executes commands entered by the user. Bash scripting is the process of creating a sequence of commands that can be executed by the Bash shell.

Example:

Print “Hello world!”, your user name and the current date:

#!/bin/bash 

whoami 
date 
echo Hello world!

Save this script to a file called hello.sh and make it executable with:

chmod +x hello.sh

Then run it:

./hello.sh
