Octavian,
I do not see how this is possible without modifying the original script at least a little. When you use IO::Tee, you will be able to tie both the LOG and STDOUT to the same filehandle, so that wherever there is a print statement - it will print in both places. By setting auto-flush ($|), you will see events in the log as they happen (or pretty close). The script you write will have to use File::Tail to constantly be checking the bottom of the log looking for a specific event, which will trigger a desired action - such as email/page.

I am not sure how to help beyond this without seeing the code of the original script, some sample output, and what "events" would like a trigger action.

Cheers - L~R

• 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).
