regarding the creation of a a child process,- fork() for itself creates just a clone of the current process, it's useless without a subsequent exec(). So after the fork() you have two (almost) identical processes, both of'em just returning from fork(). The fork return value is then used to determine whether it's child or parent - in case of parent you do the exec() then which replaces the clone with whatever process you like: if($pid = fork()) { #...this is the parent ... } elsif (defined $pid) { # this is the child... exec(<whatever executable>) } else { # error - the fork() didn't work }

Title:
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.
