Normally, unless the child processes detach from the parent's process group, signals will propagate to the children, so when you kill the parent, the children should go down as well. However, if you want to do this explicitely, you can use Proc::ProcessTable. Something like this (untested):
use strict; use warnings; use Proc::ProcessTable; my $signal=15; my $parent=shift; # Parent PID from args my $proc_table=Proc::ProcessTable->new(); foreach my $proc (@{$proc_table->table()}) { kill($signal, $proc->pid) if ($proc->ppid == $parent); }
Making this code recursive to kill the children's children is left as an exercise for the reader :) (read: it's Sunday morning and I can't be bothered to do so myself ;) ).

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.
