In that case, the code I included above is exactly what you want.

As for 50 lines at a time - it's not really happening that way. The above loops will do things line by line as they are output. I bet it's just buffered output that is the problem.

You may have to unbuffer the original script (if it's perl, use the same solution - if it's not perl, I'm not sure what you can do). However, if it normally produces even output, then just fix the monitor.pl script.

You can unbuffer the output from your monitor.pl perl script with:
$| = 1;
or as an alternative
use FileHandle; STDOUT->autoflush;
This should produce smooth, line by line output, as it is generated by the original script.

As a side note, I bet your email gets sent immediately, it is just the text output to the screen that is buffered.

  • 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.
