I have a hash that have multiple sub hashes and I want to sort
it by a sub key.
For example, I have:
$comp{$code}{$year}{profit}.
And I want to sort the $code values after the value of the
"profit" key.
Is this possible directly, or I will need to create another
hash for doing this type of sort?
You don't need another hash.
perldoc -f sort
perldoc -q "sort a hash"
my @codes = sort {
$comp{$a}{$year}{profit}
<=>
$comp{$b}{$year}{profit}
} keys %comp;
my @codes = sort {$a <=> $b} keys %comp;
If I didn't misunderstand the OP completely, I can't see how that
would do what he wants.
