    Is there any advantage to this variant? It's longer and buggy (missing chomp). It's also less clear due the weird use of => to separate two of three arguments, especially when it's also used to associate the arguments to the command.

    Either way, I just realised du is useless.

    perl -e'system zip => "-d", $_, "*exe*" for @ARGV' */*/old.zip

      TMTOWTDI    ;-)

      perl -e'system "zip", "-d", $_, "*exe*" for <*/*/old.zip>'
        That fails for paths with spaces. That may not be a problem for the OP, but it would be for me.
