My question was simply this: is there something internal that die does that is necessary to exit a script properly?

The very point of this is to provide a more detailed error message, such as you describe, so the user does indeed know what the problem is without ungraciously dumping them in the middle of nowhere.

Update: To clarify, almost 100% of the time, this scenario is usually part of processing an HTML form which is uploading something or performing some file op, such as deleting a file. If there is an error, I use HTML::Template and HTML::FillInForm to re-display the form with the error message at the top so they can try again (or at least know what happened).

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • 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.
