In the second and third examples, you forgot a final '

If you want ' print working try

perl -e "print 'hello \'\'  ' "

or

perl -e "print \"hello \'\'  \" "

(Like the first example but with \')

The second and third, wait for something because they (with -lane) mean

BEGIN { $/ = "\n"; $\ = "\n"; }
LINE: while (defined($_ = <ARGV>)) {
    chomp $_;
    our(@F) = split(' ', $_, 0);
    print 'hello   ';
}

Update: Just inverted order of things and corrected some errors.
