Found an example, where the daemonization closes STDOUT and STDIN in order to not create files. This could confuse the child process (which has no stdout). So either, maybe this works:

use Daemon::Simple; open(SAVEIN, "<&STDIN"); open(SAVEOUT, "<&STDOUT"); Daemon::Simple::init("daemon"); open(STDIN, "<&SAVEIN"); open(STDOUT, "<&SAVEOUT"); print qx("/external/command"); close(STDIN); close(STDOUT);

or you will have to redirect your output to a file

qx("/external/command > /tmp/file")

and read it back using open(), diamond and close()

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.
