in reply to Dereferencing a hash reference to a Hash of Arrays

You want to use @{...} to dereference the array reference. That is, @{$sort->{23}} will get you a list. For your specific problem, I'd do:

my $search = 'price'; my $column = 23; if (grep {$_ eq $search} @{$sort->{$column}}) { # ... }

perl -pe '"I lo*`+$^X$\"$]!$/"=~m%(.*)%s;$_=$1;y^`+*^e v^#$&V"+@( NO CARRIER'
