You must have an old perl/pod2html :)

ack "\<ARGV\>" C:\perl\5.10.1\bin\*bat

    Your 'ack' is wrong on two accounts. First of all, pod2html doesn't do anything more than using a module, and calling a single sub in that. The work is done in ..../lib/5.10.1/Pod/Html.pm.

    But even then, searching for <ARGV> or <>won't reveal much. But this is relevant:

    local(@ARGV) = @_; ... local *POD; unless (@ARGV && $ARGV[0]) { $Podfile = "-" unless $Podfile; # stdin open(POD, "<$Podfile") || die "$0: cannot open $Podfile file for input: $!\n" +; } else { $Podfile = $ARGV[0]; # XXX: might be more filenames *POD = *ARGV; } ... my @poddata = <POD>;
      Huh, my ack is wrong?

      That is what it does now, it wasn't always a module.

      It shows magic isn't used.

        It shows magic isn't used.

        So what is <POD> do if not magic?

        mkdir /tmp/aaa cd /tmp/aaa touch a.pod b.pod 'rm * |' pod2html * ls
