Re: 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!	[reply]
