in reply to Golf: reverse sort /etc/passwd by UID

Here's a Perl 6 solution, works with current Rakudo. Not really golfed, just the way you'd write it in a terse way:
$ cat /etc/passwd | perl6 -e '.say for lines.sort: +*.split(":")[2]'

The nice part is that Perl 6's sort method automatically does the Schwartzian transform for you if the comparison code object takes only one argument.

[thezip]: Is there an analogy for '&' (ie. run commandline process in background) for Windows commandline?
[Corion]: thezip: start "some title" path\to\that\ application, but that will open another console window
[Corion]: thezip: If you want to confuse your users, use system(1, "that\\command" );, which will make Perl launch it in the background
[Corion]: That will keep the console window open even though the user can't type into it anymore
[thezip]: So I have a script that generates a log file. After script completion, I want tohave VIM open this logfile.
[thezip]: i don't get the command line "back" until I close VIM. No what I want to happen...
[thezip]: I currently don't have access to CYGWIN, else I'd just do a tail -f on the logfile.
