You probably want to sort the hash by fields first. Here's an example.
#!/usr/bin/perl use strict; use warnings; #by davido of perlmonks # Name Sex Age IQ Hair Eyes my %hash = ( 'Lisa' => [ 'F', 6, 150, 'Blonde', 'Blue' ], 'Homer' => [ 'M', 40, 105, 'Bald', 'Blue' ], 'Bart' => [ 'M', 9, 120, 'Blonde', 'Brown' ], 'Marge' => [ 'F', 36, 135, 'Blue', 'Blue' ], 'Maggie' => [ 'F', 1, 130, 'Blonde', 'Blue' ] ); # Assume that @criteria is actually obtained at runtime. my @criteria = ( 0, 2, 3 ); my @comparisons; my ( $sample_key, $sample_value ) = each %hash; foreach ( @criteria ) { push @comparisons, "\$hash{\$a}[$_]" . ( $sample_value =~ /^\d+$/ ? " <=> " : " cmp " ) . " \$hash{\$b}[$_]"; } my $routine = join " || ", @comparisons; my @sorted; eval "\@sorted = sort { $routine } keys \%hash" or die "Ick!\n$@\n"; print $_, "\n" foreach @sorted;

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
