Since Perl integrates well with the shell, you can also transition stepwise into a full Perl implementation.

For example, start with a command-line script:

>tail -f /var/log/ldap.log | perl -ne 'if ( /connection_input: conn=11/ ) { system ( "send an email" ); system ( "restart ldap" ); }'

Then move the code into a Perl script file:

>tail -f /var/log/ldap.log | process.pl

Then take over the function of tail in Perl:

>process.pl

And finally maybe replace some of the system calls with Perl equivalents (eg, Mail::Sendmail)...

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.
