Java's compareTo() function equivalent in Perl?

Question

What's the Perl function that achieves the same thing as compareTo() in Java? I know about eq and ne but I want to compare to see if one string is greater than another.

You'll get better answers to questions like this if you explain exactly what `compareTo` does in Java. Not all Perl programmers know Java. — cjm, Aug 23 '10 at 21:01

You actually have cmp (for strings) and <=> (for numbers) operators. See the Equality Operators section in perlop.

Example:

print "foo" cmp "bar"; # prints 1

gt should do the trick

Edit: actually, cmp would be more similar to compareTo(), gt would just tell you if the string is greater than then the other.
