Did you mean something like this? `#!/usr/bin/env perl use strict; use warnings; use feature qw(say); use Data::Dump; my %hash = ( test1 => [ 1, 2, 3 ], test2 => [ 4, 5, 6 ] ); dd map { scalar @{ $hash{$_} } } keys %hash; __END__ karls-mac-mini:playground karl$ ./hash.pl (3, 3)` [download] Regards, Karl ŤThe Crux of the Biscuit is the Apostropheť `perl -MCrypt::CBC -E 'say Crypt::CBC->new(-key=>'kgb',-cipher=>"Blowfish")->decrypt_hex($ENV{KARL});'`Help	[reply] [d/l] [select]

Size != Length. `$ perl -MDevel::Size=total_size -wE'my%h=(test1=>[1..3],test2=>[4..6]) +;say"$_ -> ",total_size$h{$_}for keys%h' test1 -> 160 test2 -> 160 $ perl -wE'my%h=(test1=>[1..3],test2=>[4..6]);say"$_ -> ",scalar@{$h{$ +_}}for keys%h' test2 -> 3 test1 -> 3` [download] Enjoy, Have FUN!

What exactly is the value of test1 and what is the "size" you are expecting? The text you show isn't Perl code and doesn't make sense. Cheers Rolf _{(addicted to the Perl Programming Language and ☆☆☆☆ :) Wikisyntax for the Monastery}	[reply]

Re^2: Size of the hash value by Eily (Monsignor) on Feb 22, 2018 at 10:02 UTC
Except this will increase the array size (append undef to each array). So it will give a different result on each call, always out of date.	[reply]
Re^3: Size of the hash value (nullipotent) by hippo (Archbishop) on Feb 22, 2018 at 11:55 UTC
Indeed so. If harishnv requires nullipotence then another similar approach could be employed. Such as `say $#$_ + 1 for values %hash;` [download]	[reply] [d/l]

Read split `#!perl use strict; my %hash = ( test1 => "1 2 3", test2 => "4 5 6", ); for my $key (keys %hash){ my $lines = split "\n",$hash{$key}; print "$key $lines\n"; }` [download] poj	[reply] [d/l]

Sure. What you posted is raw data. There is no hash so there are no hash values. Smartalecky answer i know but you posted data not a data structure	[reply]
