Although perl normally makes things pretty for the programmer, file listings aren't kept by the OS in any particular sort order. To sort it would require extra processing, and a lot of users of readdir don't care if it's sorted or not, or even don't want to read all of a directory listing, so it makes sense for perl not to do the extra work by default.

If you'd structured your code to read the dir into an array, and then work through that array doing work on each entry, then it'd be trivial to sort the list items however you want. Also, it'd allow you to deal with any errors reading the dir more flexibly (should you want to produce no output, or a specific error if their is a problem with readdir()) This is generally a good programming practice if you want to reuse code, or want to change where a program sources its data from.

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 or How to display code and escape characters are good places to start.
