If you can't use nohup for some reason then you can still "daemonize" your script. Someone mentioned POSIX::setsid() - I have had good luck with using the following subroutine:
sub daemonize { my $childpid; if(($childpid = fork()) < 0) { die("can't fork: $!"); } elsif($childpid > 0) { exit(0); # parent - exits } (setpgrp() != -1) || die("Can't change process group: $!"); $SIG{HUP} = 'IGNORE'; if(($childpid = fork()) < 0) { die("can't fork: $!"); } elsif($childpid > 0) { exit(0); # parent - exits } chdir("/"); umask(0); }
This code was borrowed from Stevens' "Unix Network Programming" - a book that should be in every programmers bookshelf...

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.
