Step 1: Write A Basic Bash Script

As always the best way to learn about something is to jump into it, so lets practice writing a very basic script that will print your name onto into the terminal.

Open a text editor and create a new file on your desktop called ‘BashScript.sh’ end enter the following text:

#!/bin/sh
echo "Hello world from Bash!"

You should be able to figure out what happens in this script. Firstly (and the less obviously) we specify the shell we will be using for the script, in this instance ‘sh’ (if you don’t know what a ‘shell’ is don’t worry too much, its not required to write basic Bash scripts. You just need to know that the line is there for now) The second line simply prints ‘Hello there!’ onto your terminal window.

Let’s try running it. Open a new terminal window and type the following:

. /Users/username/Desktop/BashScript.sh

If you see “Hello world from Bash!” it all worked!
