You're getting that error because you're defining a package-global variable ($name) which is not allowed under strict. (Well, it's allowed, but it requires an explicit package name, which probably does not surprise you.)

The way to do what you want is to create a lexical variable with my.

#!/usr/bin/perl -w 

use strict; 
print "Hello, I am Komodo what is your name? "; 
my $name = <STDIN>; 
chomp $name; 
print "Hello, $name!\n";
