Yes, of course.
Just for curiousity, i tried the following:
#!/usr/bin/perl -w
while(<>) { print };
seek(STDIN, 0, 0) or die;
print "-----PASS 2-----\n";
while(<>) {print}
and ran it with:
> ./t.pl < t.pl
and it did
read the file twice! How come?
(I was expecting an error like 'non-seekable file' or so.)
When doing
>cat t.pl | perl t.pl
it died
where it should have (i.e. in the seek()).
