How to get the results of long running commands in pypsexec?

Question

I'm using pypsexec to connect to a remote Windows machine. I've to find a list of files with a certain extension. This is what I'm doing right now.

command = "dir /b/s *.py"
client.run_executable("cmd.exe", arguments=f"/c {command}", asynchronous=True)

I wasn't receiving any responses at first when I didn't use the asynchronous parameter. Having read the documentation, I can see that long-running tasks (like mine) should use this parameter. However, it doesn't provide explicit instructions on how to get the output after the job is finished.

Thanks in advance!

Answer 1

This is because you can't get the output. See https://github.com/jborean93/pypsexec/blob/master/pypsexec/client.py#L436-L466

if not interactive and not asynchronous:
    [...] # Here is where stdout and stderr is set
else:
    stdout_out = None
    stderr_bytes = None

[...] # Here is some code that doesn't change stdout_out or stderr_bytes

return stdout_out, stderr_bytes, return_code

As you can see when using asynchronous=True the stdout and stderr will always be None
