I have this statement;
foreach my $key ( keys %filehash ) {
print "$key $filehash{$key}->[0]\t\t\t$filehash{$key}->[3]\t
$filehash{$key}->[2]\t $filehash{$key}->[1]\n";
}
but wish to sort the output by $filehash{$key}->[0]. Is it possible? How
do I do this?
I can't make a separate hash of the value because of multiple values of
the value
http://perldoc.perl.org/perlfaq4.html#How-do-I-sort-a-hash-(optionally-by-value-instead-of-key)%3f
( http://goo.gl/Ol31 )
only shows the sorting where the hash has only a scalar.
TIA
Owen
