in reply to Does IPC::Open3 uses temporary file?

Speaking as a veteran of many fights with IPC::Open3, I would recommend to you that there are other simpler and less problematic methods to separately capture STDOUT/STDERR from subprocesses. IPC::Run is much better at doing this simply and reliably.

There are several other CPAN modules that appear to do this in an even simpler manner than IPC::Run; IO::CaptureOutput, and System2 are two examples. I haven't used these two modules per se, so caveat programmor.

Open3 is actually pretty powerful, but with the power comes complexity -- using it feels like programming in C, and it's very easy to get yourself deadlocked if you don't manage your io handles carefully.

    Your post was of really much help to me, thanks.

    I tried open3 and almost succeeded, but, while asimptotically reaching final result, I still had no success on that way.

    I gained my goal using namely IPC::Run. I was stuck several times with "Win32 limitations" described in that module, however, but finally I got it.

    Finally, a program that implements quite simple thing (from unexperienced point of view), become quite complicated, but it works and hopefully does not stuck.

    I can show a code, if anyone interested on what it finally looks like.

    Best regards,
