How do I process an entire hash?

Current Perl documentation can be found at perldoc.perl.org.

Here is our local, out-dated (pre-5.6) version:

Use the each() function (see each) if you don't care whether it's sorted:

    while ( ($key, $value) = each %hash) {
        print "$key = $value\n";
    }

If you want it sorted, you'll have to use foreach() on the result of sorting the keys as shown in an earlier question.
