Can anybody tell me where i am wrong?

First you tell us why you think something's wrong. In what way does it not do what you expect?

Second, your approach is very fragile, there are several ways to call your script that will break it (for example by using relative paths, or symlinks to the script).

Consider locking a particular file instead; you should find some examples here on perlmonks with Super Search.

Perl 6 - links to (nearly) everything that is Perl 6.

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
