in reply to how to sort this?

What do you want to sort it by? Sort it like strings? Like numbers? By extracted integers? Or a combination of all of the above?

Helps to know the requirements before starting an implementation.

      Hi sen try this it gives your exact output, 

      #!/usr/local/bin/perl

@a1 = qw/1x1 1x12 12x3 10x1 4x12 4x1 1x1 22x3 2x1 4x0 12x1 1x2/;
@out = sort {
 (split 'x', $a, 2)[0] <=>
 (split 'x', $b, 2)[0]
}
sort {
 (split 'x', $a, 2)[1] <=>
 (split 'x', $b, 2)[1]
}@a1;

print "@out";
