Example 1: Hello Shell Scripting

Aim

To write a simple shell script to print “Hello Shell Scripting” in the terminal.

Steps:
Create a shell-scripts folder inside workspace folder in your home folder. This is just to keep all your project files organized.

 mkdir -p ~/workspace/shell-scripts

Go inside the shell-scripts folder.

 cd ~/workspace/shell-scripts

Inside this folder create a file called hello.sh.

 touch hello.sh

Open this file in a text-editor

 gedit hello.sh

If you have Sublime-Text installed, you can use-

 subl hello.sh

Now write the shebang for the script.

 #!/bin/bash

Below it write the command to print “Hello Shell Scripting” in the terminal.

 echo Hello World

Now save the file and close the text-editor.

Use chmod to make this script an executable.

 sudo chmod +x hello.sh

Run the script.

 ./hello.sh

If done correctly you should see the following output in the terminal-

 Hello Shell Scripting

Code

 #!/bin/bash
 echo Hello World
