So, if I'm reading this right, you've got a bunch of numbers like so:
64/2829
1/349834
37823/8338
5/989328
And you want them sorted like this:
1/349834
5/989328
64/2829
37823/8338
Here:
sub sortbyfirst {
my ($f_a, undef) = split(/\//, $a);
my ($f_b, undef) = split(/\//, $b);
return $f_a <=> $f_b;
}
@sorted = sort sortbyfirst @numbers;
Note: Untested.
This won't be superfast... If you've got a huge list, or this runs constantly, look into the tye transductor, illustrated here.
