I bet mine runs with 1/4th the CPU.
Except that for small to medium sized files, it doesn't matter and the additional programming (and debugging) time dwarves the running time. And for really long files, your program might actually be slower, or even fail to finish as it will consume significant amounts of memory. The elegant one-liner, consisting of several tools that do one thing well won't suffer from memory problems, as 'sort' knows when to switch to using temporary files.

Having said that, I would have written the one-liner as:

awk '{print $6}' /var/log/httpd/access_log | sort | uniq -c | sort -n | head -10

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