  Matthias did answer your question.  Computers don't think in terms of
"lines" in a filesystem.  Therefore you have to do the work yourself.  
What you are asking for is not possible.

  An explaination is available in the Perl FAQ in the Files & Formats
section.  The FAQ is "How do I change one line in a file/delete a line in
a file/insert a line in the middle of a file/append to the beginning of a
file?" and the answer is at
<http://www.perl.com/pub/doc/manual/html/pod/perlfaq5.html#How_do_I_change_one_line_in_a_fi>.
