Very nice. I would only add a few more.

If you are working with a database, it is often worthwhile to move the sort out of Perl and into an SQL statement. Likewise when handling files in a Unix environment it is sometimes best to just resort to the Unix sort utility. Another external "sort this file" module to play with is File::Sort. And I have a personal fondness for using the BTREE option of DB_File to maintain a sorted data structure.

These are all worth knowing about, but moving sorts into SQL is particularly effective for saving headaches. While sorting the output yourself may be a fun demonstration of complex Perl manipulations, the database is likely to be faster, and (particularly if you are sorting on dates!) is likely to save headaches.

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.
