You can cut one more byte by using the -F option instead of -n: Try it online!

Joe: i was talking about the }{ "injection", not just about the well known -n option. One might not expect that the code string actually technically is wrapped by the while loop code string before the execution, not only just that it somehow works like as if it was wrapped..

update - yet shorter - comments

| Jul 3, 2014 at 14:49 | comment | added | mykhal | Dennis: anyway, it's ingenious hack, i can't see it anywhere in the docs. please let me know if you have some links to discussions on this - it's difficult to search (i wish google could do regexp search) | |

Yes, -n wraps while(<>){...} around the code. I avoid editing other users' code. Too easy to make a mistake, some things only work on some computers, etc.

Dennis: very interesting, it looks like a typo.. wth is this? i've had some variants using -n and END{}, but they were always longer.. feel free to update the answer, if you want

Shorter and no error messages: perl -ne 's/./$h{uc$&}++/eg}{print sort{$h{$b}<=>$h{$a}}A..Z'
