Intercepting stdout of a subprocess while it is running
If this is my subprocess:
subprocess
Popen with conflicting executable/path
I’d like to call the “convert” utility from ImageMagick from my Python script using Popen, like so:
Run child processes as different user from a long running Python process
I’ve got a long running, daemonized Python process that uses subprocess to spawn new child processes when certain events occur. The long running process is started by a user with super user privileges. I need the child processes it spawns to run as a different user (e.g., “nobody”) while retaining the super user privileges for the parent process.
Run Process and Don’t Wait
I’d like to run a process and not wait for it to return. I’ve tried spawn with P_NOWAIT and subprocess like this:
subprocess: deleting child processes in Windows
On Windows, subprocess.Popen.terminate calls win32’s TerminalProcess. However, the behavior I see is that child processes of the process I am trying to terminate are still running. Why is that? How do I ensure all child processes started by the process are killed?
Use subprocess to send a password
I’m attempting to use the python subprocess module to log in to a secure ftp site and then grab a file. However I keep getting hung up on just trying to send the password when it is requested. I so far have the following code:
Using subprocess to run Python script on Windows
Is there a simple way to run a Python script on Windows/Linux/OS X?
How to write to stdout AND to log file simultaneously with Popen?
I am using Popen to call a shell script that is continuously writing its stdout and stderr to a log file. Is there any way to simultaneously output the log file continuously (to the screen), or alternatively, make the shell script write to both the log file and stdout at the same time?
Is it possible to run function in a subprocess without threading or writing a separate file/script.
import subprocess def my_function(x): return x + 100 output = subprocess.Popen(my_function, 1) #I would like to pass the function object and its arguments print output #desired output: 101 I have only found documentation on opening subprocesses using separate scripts. Does anyone know how to pass function objects or even an easy way to pass function … Read more
OSError: [WinError 193] %1 is not a valid Win32 application
I am trying to call a Python file “hello.py” from within the python interpreter with subprocess. But I am unable to resolve this error. [Python 3.4.1].
