could you please show me how? From the docs:

fork() creates a new process by duplicating the calling process.

I don't wanna replicate the Perl script but spawn a PS window.

> tail and grep for Windows

does this offer the -f option? I don't think so.

> is File::Tail usable on Windows ?

File::Tail seems overkill, and like the title suggests there might be problems on Win

get-content -wait is a built-in in all modern Win versions

> You can also use Win32::Process to create and kill the subprocess.

That's a very good idea, thanks! :)

> You can also use Win32::Process to create and kill the subprocess.
That a very good idea, thanks! :)

In case it's of use, some sample code I wrote years ago to cleanly kill processes after a timeout period:

• Timing Windows commands - uses Win32::Process
• Re: Timing Windows commands - uses Win32::Job (for my application, I much preferred this version to the Win32::Process one above)
• Timing and timing out Unix commands - Unix version using fork, exec, kill, waitpid
BTW, I never use fork/exec on Windows, due to limitations and general weirdness of perlfork emulation under Windows.

Yes, i know you don’t want to spawn…

But consider something like this:

use strict;
use warnings;
use threads;
use MCE::Hobo;

my $hobo = MCE::Hobo->create( sub {
    …;
});

my $pid = $hobo->pid();

# $hobo->join();

Update:

«I though about sending a 'kill', but Perl doesn't seem to give me the PID.»

Now you have one to kill.

Thanks, very helpful! :)

Hello LanX,

You are already forking!

From system

> Does exactly the same thing as exec, except that a fork is done first and the parent process waits for the child process to exit.

There are no rules, there are no thumbs..
Reinvent the wheel, then learn The Wheel; may be one day you reinvent one of THE WHEELS.

that's the inner implementation.°

just show me how to do it with fork and you'll see how complicated it is.

°) and I wouldn't be too sure it's ported the same way to windows.

IIRC is fork implemented with threads there, so there might be issues.
