The problem with looping on the input from named pipes is that after the first read you're left with an EOF for the second read1, so the loop exits. Subsequently you can't loop on a named pipe without working some serious voodoo (over-riding CORE::GLOBAL::eof()?). So this provides with many excuses to do dubious things such as using goto(), labels and (dum dum dum) infinite loops. Personally I'd go with an infinite loop opening the FIFO on each iteration, or take have a good long think about it. Good luck!

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