How do I process an entire hash? Can't Post

(From the Perl FAQ)

How do I process an entire hash?

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

Code
    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.
