Get value
echo -n Password:
read USER_VALUE
echo
echo $USER_VALUE
Get password
This hides the input from the terminal.
Based on SO discussion.
Some shells can do this in one line:
read -s -p "Password:" USER_PASSWORD
echo $USER_PASSWORD
Otherwise in two lines as echo -n and read.
echo -n Password:
read -s USER_PASSWORD
echo
echo $USER_PASSWORD
Some shells won’t do echo -n so then use printf.
