Multi Line comment in Shell Script

We know that we can comment a line using '#' in Shell Script, but what if we want to comment a huge block of code? If we use '#' to comment that block then this can be very tedious task. Rather than using single line comment we can use multi line comment. In this tutorial i will show you how to use multi-line comment in Shell Script.

In Shell Script multi line comment can be of form 

<<'COMMENT'

what ever written here is a comment

COMMENT

Let see example of multi line comment

#!/bin/bash
echo "Hii guys"
#starting of mullti line commnent
<<'COMMENT'
read a
echo "No line in this block will execute"
COMMENT
echo "Hello Guys"
exit
