Shell Script Comments

We can use both the single line and multi lines comment in shell script. For using a single line comment we use # in front of the line and for a multi lines comment we use : ‘ ‘ . Let’s see and example:

#!/usr/bin/env bash
#Single line comment

echo "hello world!"

: 'This is a multi
line comment
'
echo new world!

Save this as comment_ex.sh and run as like:

$ bash comment_ex.sh

Output:
hello world!
new world!

You can see the commented texts are ignored.
