Perl is really just one of a number of excellent (or not quite so :) tools to accomplish a given task. For example, If you need a script that has to run perpetually and rotate logs once in a while, well, you still can write a perl script to do the actual log rotation and crontab to schedule your script's work. Of course, a programmer with limited exposure to Unix system functionalities (or lack thereof), yet ample Perl programming experience, could write a daemon to also run perpetually, yet do the same job, and probably do it good.

Now, to me the question of when to not use Perl is actually rather straightforward. Mostly, the answer would be 'yes' if I'm dealing with CGI, sysadmin, or any other tasks that could be accomplished by a cleverly crafted 'script' (Perl is a clever language :). However, if there's a task where you clearly see that no script would help, certainly Perl wouldn't be the answer. For example, lack of processing power of a given computer is certainly a 'computer problem'. While, you could optimize your Perl script to squeeze maximum performance, replacing your processor or adding a couple extra MB of RAM might help. Hack, it does sound like a double edged sword in certain cases, doesn't it? ;-)

$"=q;grep;;$,=q"grep";for(`find . -name ".saves*~"`){s;$/;;;/(.*-(\d+) +-.*)$/; $_=["ps -e -o pid | "," $2 | "," -v "," "];`@$_`?{print"+ $1"}:{print" +- $1"}&&`rm $1`; print$\;}

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 editor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
