    <p><strong>Update:</strong> Based on your comments, I get the feeling that your programs are not examples of best practices on Linux or Windows. However, I am sure, when reading the documentation for <code>Win32::Process</code>, you noticed that you can call the <code>Kill</code> method on the process to terminate it. So, I changed the example below to do that.</p> <p>Your chances of getting useful help increase exponentially if you provide real code. Here are the arguments to <code>Win32::Process::Create</code>:</p> <p><strong><code>$iflags</code>:</strong> flag: inherit calling processes handles or not</p> <p>Now, I am not sure if you are trying to capture the <code>STDOUT</code> of the second process or if you are trying to have its <code>STDOUT</code> output show up in the same console as the parent.</p> <p>If the latter, then the following scripts illustrate one way of doing that:</p> <h3>parent.pl</h3> <pre><code>#!/usr/bin/perl use strict; use warnings; use Win32; use Win32::Process; $| = 1; my $p; print "Starting child process ... \n"; Win32::Process::Create( $p, 'c:/opt/perl/bin/perl.exe', 'perl hello.pl', 1, NORMAL_PRIORITY_CLASS, '.', ) or die Win32::FormatMessage( Win32::GetLastError() ); print "Waiting three seconds before killing 'hello.pl'\n"; for (1 .. 3) { print; sleep 1; } $p-&gt;Kill(0) or die "Cannot kill '$p'"; </code></pre> <h3>hello.pl</h3> <pre><code>#!/usr/bin/perl $| = 1; print "Hello World\n"; print "Sleeping 1000 seconds\n"; for (1 .. 1000) { sleep 1; print '.'; } </code></pre> <h3>Output:</h3> <pre> Starting child process ... Waiting three seconds before killing 'hello.pl' 1Hello World Sleeping 1000 seconds 2.3. </pre> <p>Now, <strong>I am still not sure why you are using <code>Win32::Process</code></strong>. Unless there is a specific reason to tie your script to <code>Win32</code>, I would recommend using standard Perl facilities. For example, read <a href="http://perldoc.perl.org/functions/open.html" rel="nofollow noreferrer"><code>perldoc -f open</code></a> and <a href="http://perldoc.perl.org/perlipc.html" rel="nofollow noreferrer"><code>perldoc perlipc</code></a> (see esp. <a href="http://perldoc.perl.org/perlipc.html#Using-open%28%29-for-IPC" rel="nofollow noreferrer"><em>Using open for IPC</em></a>).</p> <p>Explain your question better to get answers that address your particular situation rather than generalities.</p>

    1. COIf I create the process through the system command, I was not able to find any method to terminate the process on win32. On Linux I just used system("kill -9 -$$") to kill the perl script and all it's children but couldn't find anything so simple on Windows

    2. COhttp://speculation.org/garrick/kill-9.html All kidding aside, I find `system("kill -9 -$$")` suspect. `fork` works on Windows: `fork` your children, save their `pid`s and `wait` on them or `kill` them as you see fit. I prefer http://search.cpan.org/perldoc/Parallel::ForkManager

    3. COTried that and would love to do that - however, if I fork() and then call my child script through exec or system, the PID of the exec'd process is different from the PID returned by fork.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
