Further to the excellent response from Tux, I tend to use the form #!/usr/bin/env perl which pulls the version of perl from your environment - this is handier if, as I have, you one, or other, or both, of the following situations...

• Different versions of perl against which you are(required to be) testing/running your code &/or...
• Different *NIX platform configurations on which you are testing/running your code

The above is, of course, moot if you have to run on Windoze, where all sorts of other problems come into play e.g. as you suggest, the shebang line is ignored etc. hence work-rounds have to be used e.g. batch files containing the full perl script (incl. the shebang line) together with the -x CLI option (see perlrun).

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
