How to kill a python child process created with subprocess.check_output() when the parent dies?
I am running on a linux machine a python script which creates a child process using subprocess.check_output() as it follows:
subprocess
What’s a good equivalent to subprocess.check_call that returns the contents of stdout?
I’d like a good method that matches the interface of subprocess.check_call — ie, it throws CalledProcessError when it fails, is synchronous, &c — but instead of returning the return code of the command (if it even does that) returns the program’s output, either only stdout, or a tuple of (stdout, stderr).
subprocess “TypeError: a bytes-like object is required, not ‘str'”
I’m using this code from a previously asked question a few years ago, however, I believe this is outdated. Trying to run the code, I receive the error above. I’m still a novice in Python, so I could not get much clarification from similar questions. Does anyone know why this is happening?
running multiple bash commands with subprocess
If I run echo a; echo b in bash the result will be that both commands are run. However if I use subprocess then the first command is run, printing out the whole of the rest of the line.
The code below echos a; echo b instead of a b, how do I get it to run both commands?
running a command as a super user from a python script
So I’m trying to get a process to be run as a super user from within a python script using subprocess. In the ipython shell something like
Passing double quote shell commands in python to subprocess.Popen()?
I’ve been trying to pass a command that works only with literal double quotes in the commandline around the "concat:file1|file2" argument for ffmpeg.
What’s the difference between subprocess Popen and call (how can I use them)?
I want to call an external program from Python. I have used both Popen() and call() to do that.
Display realtime output of a subprocess in a tkinter widget
My question is almost the same as this one:

but a step further.
How to suppress or capture the output of subprocess.run()?
From the examples in docs on subprocess.run() it seems like there shouldn’t be any output from
Cross-platform subprocess with hidden window
I want to open a process in the background and interact with it, but this process should be invisible in both Linux and Windows. In Windows you have to do some stuff with STARTUPINFO, while this isn’t valid in Linux:
