I've got an array full of hashrefs:
my @a = ( {N => '10.1.2.1'},
{N => '10.1.9.1'},
{N => '10.3.5.1'},
{N => '10.1.1.3'},
);
I want to sort this array, and print. I expect the output resemble:
10.1.1.3
10.1.2.1
10.1.9.1
10.3.5.1
I've fumbled with this for a while, and the closest I've come to is:
my @s = map { $_ -> [0] }
sort { $a->[0] <=> $b->[0] ||
$a->[1] <=> $b->[1] ||
$a->[2] <=> $b->[2] ||
$a->[3] <=> $b->[3] }
map { [ $_, split /\./ ] } $a->{N};
but that simply fails to produce. I've replaced $a->{N} with multiple
variations, but I'm confused.
If someone can give me code, I'd also appreciate a clue.
thanks,
