Learn Shell Scripting: Hello World

This is an introductory post to Shell Scripting which will be followed by many other each highlighting a feature of shell scripting. The material provided here was taught as a part of university course and not created by me.

01 Hello World

#!/bin/bash

# This is simple hello world script.
# We can write comments on lines
# starting with hash (#) character

echo Hello World!
exit 0

# It is good habit to return 0 if
# script ends successfully.
