Let's say you want to prompt a user for input, like this.

What is your name?

The following markup can be used to produce the prompt. 

#!/usr/bin/perl
use strict;
use warnings;

print "What is your name? \n";
my $name = <STDIN>;
chomp $name;

In this example, whatever the user types at the prompt will be stored in a variable named $name. The $name variable can be printed to display the users name.

print "Your name is $name \n";
