in reply to Delete space at the end of a hash element

Or using map function, with hdb data like so:

use warnings; use strict; use Data::Dumper; my %hash = ( "apples " => 4, "oranges " => 5 ); %hash = map { my $val = $hash{$_}; s/\s+$//; $_, $val } keys %hash; print Dumper \%hash;

If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.

    So you are completely rebuilding the hash in one go, rather than adding/removing one entry at a time. That's far more elegant!
