in reply to Split on every second character

Or still using split, you can just drop every second element from the result list:
$ perl -le '@l = grep {$i++ % 2} split /(..)/, "010203040506"; print j +oin "|", @l'
But the solutions provided by other monks are definitely nicer.

    I agree that some variation of an approach using  m/..?/g or  unpack() is better, but a more concise  split() solution would be:

    >perl -wMstrict -le "print for grep length, split /(..)/, '0001020304101112';" 00 01 02 03 04 10 11 12
