If you need the PID you might want to look at fork and exec. fork will return the childs pid, you can then have the child exec the system call. As I understand it, this is what system() does at it's core. Check out perldoc -f fork and perldoc -f exec for examples and details. I wrote the following that seems to work, no error checking though.
use strict;
use warnings;
$SIG{CHLD} = '"IGNORE"';
my $child = fork();
if ($child) {
print "I'm the parent, I think I'll wait for the child $child...\n
+";
waitpid($child, 0);
} else {
exec ("ls");
}
Good Luck,
Ira.

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).
