The command string consists of "filename.exe instruction1 instruction2

find the file instruction1".
How do I pass command line instructions in process.Process? I tried a
list with the same
result.
If you're wondering why I'm switching, it's because I'm working with a
poorly behaved 3rd party program that causes a severe memory leak, and I

Hi.
I have a python script under linux where I poll many hundreds of
interfaces with mrtg every 5 minutes. Today I create some threads and
use os.system(command) to run the process, but some of them just hang.
I would like to terminate the process after 15 seconds if it doesn't
finish, but os.system() doesn't have any timeout parameter.
Can anyone help me on what can I use to do this?

This has been driving me insane for the last hour or so. I have search
everywhere, and nothing works. I am trying to use the subprocess module
to run a program and get its output line by line. But, it always waits
for the process to terminate and then return the output all at once.
Can someone please show me some code that actually works for this sort
of thing? It doesn't even have to use the subprocess module. Don't
worry if the code...

Hi,
I am trying to communicate with a subprocess via the subprocess

When I use os.popen(cmd,'w'), I find that under windows, the stdout
of the child process disappears, instead of appearing in the DOS window
the script is invoked from. eg:
C:\type foo.py
import os
import sys
file = os.popen("nslookup", 'w')
file.write("google.com\n")
file.close()

Hi,
I've used subprocess with 2.4 several times to execute a process, wait
for it to finish, and then look at its output. Now I want to spawn
the process separately, later check to see if it's finished, and if it
is look at its output. I may want to send a signal at some point to
kill the process. This seems straightforward, but it doesn't seem to
be working.
Here's my test case:

Ok, I re-phrase my question:
there is a batch file that executes a exe file. The batch just works
if run from command prompt and produces output to standard output and
the file.
Now, I try to call the same batch file from subprocess.Pope() call.
The batch file gets called and that internally also calls the exe

I have one script (Match1) that calls a Fortran executable as a
sub-process, and I want to write another script (Match4) that
spawns off several instances of Match1 in parallel and then waits
until they all finish running. The only way I can think of doing this
is to call it as a sub-process, rather than directly.
I'm able to get Match1 working correctly in isolation, using the
subprocess.Popen command, but calling an instance of Match1...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.
