Bash Script wait for user Input Command

If you are writing a bash script and you are fetching input from the user and you want to wait for the user input, then you can make use of the read command with a -p (prompt) option.

Let's take a look at an example script.

Example:

#!/bin/bash

read -p "Enter Your Name: " user_name 
echo "Hello: $user_name"

./script.sh 
Enter Your Name: Sam
Hello: Sam

You will see that the script waits for user to enter their name and only returns when enter key is pressed.
