Interactive user input is a vital feature if your scripts are going to provide rich functionality. To facilitate this sort of data capture, we use the read command:
Leveraging the read command to capture user input
#!/bin/bash
echo "What is your name"
read name
echo "Hello $name"
You can also use the -p and -sp options to set a prompt or silent prompt as necessary
Example Script
#!/bin/bash
read -p 'Username: ' username
read -sp 'Password: ' password
echo "Hello $username, your password is now set to $password"
