Re^2: Killing subprocess in windows

> instead of your unusual syntax, you can try to fork

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.

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

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();` [download] Update: «I though about sending a 'kill', but Perl doesn't seem to give me the PID.» Now you have one to kill. «The Crux of the Biscuit is the Apostrophe»	[reply] [d/l]

Hello LanX, > (about fork) I don't wanna replicate the Perl script but spawn a PS window. You are already forking!

that's the inner implementation.° just show me how to do it with fork and you'll see how complicated it is. update °) 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. Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply]
