QUESTION
I am able to do most things inside the dir, but I can't cd out of it, trying /bin/sh causes the shell to freeze.
...ANSWER
Answered 2021-Jun-14 at 22:06Because everytime you send a command a new shell is created in the original folder.
To set an other working directory you have to send cd /to/other/dir && yourcommand
You can try setting the root folder for the new shell terminal:
QUESTION
Whenever I run this program, it completes the first function perfectly and then ends the program before doing anything else. How can I allow the other two functions to run?
...ANSWER
Answered 2021-Jun-14 at 17:28This isn't doing what you think it is. When you run su, just as the function says, this runs as a subprocess. That subprocess will start as my_user and immediately exit, but your Python process is unaffected. You will still be the original user.
You can feed commands into that subprocess, assuming you need to run things as that other user, but your process isn't going to change.
Followup
subprocess.call waits for the command to finish. The su command is going to create a new shell, logged in as the new user, and that shell will present a new prompt to you. You probably thought your Python script had ended and you were back at the original prompt, but that's not the case. The prompt you're seeing is from su, and you are the new user. If you press Ctrl-D, then the su will exit, your script will continue, and you'll see your script type "user switched to my_user". Thus, you are nested several shells deep and don't realize it. ;)
QUESTION
I've written a Pi Hardware Interface Server (phis) that uses http protocol to control the hardware connected to my Raspberry Pi (relays, analog measurements, etc). It processes simple requests and responds with plain text. It has been working flawlessly for years and I have written extensive browser-based interfaces to the system. Here's the basic structure:

I had forgotten to close the connected and listening sockets in the forked child, which were inherited by the spawned daemon and stayed open as long as it runs. Here's the code I'm using to spawn a process that will be left running (daemonized):

I'm trying to do some tests dumping data from one database to another with mysqldump. The mysqldump is set in PATH, and the command runs perfectly in the CMD interface, or via a .cmd. It seems to run ok in python wrapped in a simple try/except block, but I don't get any result in the target database.
Working with: MariaDB 10.1 & 10.5 / Python 3.9
The command looks similar to this:

QUESTION
I'm pretty new to python and tkinter so I'm struggling with creating a script that reads the terminal output into a label or Gui in tkinter. I've searched around and can't find any tutorials on how to do it, a lot of forums have specific or old code which makes it really difficult to adapt especially for a beginner. The code that I found that looks like it will work best for what I'm trying to accomplish was made by jfs, the only problem is that I keep getting errors which for the life of me I cant figure out.
Here is the code:

Answered 2021-Jun-10 at 14:10I have the problem too, this was my solution. I post it on [https://github.com/ianfun/notes/blob/main/editor/main.py].

I cannot found grate terminal like vscode in python.
note:use key right to select
you can read idlelib run.py

QUESTION
I've been breaking my head over this for quite some time and hope to get some support here. I have an array containing multiple objects.
Every object represents a production process comprised of subprocesses made up of inputs and outputs. These processes run in line. Meaning, that the output of one process will become the input for another process. However, I have no idea in which order.
I am trying to figure out the sequence the main processes need to be run in. Our system can't tell me and now I have 5000interdependant processes that need sorting.
Here an example of how the array is formatted. As you can see Inputs have an origin flag. At least we know whether an input is taken from a warehouse or is produced somewhere upstream. If I were to sort this manually the order would be Process3, then Process 2, then Process 1. Process 1 requires the material with the id="ID3" as input, which is produced in process 2 (under subprocess 2). While Process 2 requires the material "ID5" which is produced in process 3. Anybody have an idea how to solve this nightmare?
Thank you sooo much!!!
...ANSWER
Answered 2021-Jun-10 at 13:20As I said in the comments, what you seem to have is a graph theory problem :-)
- The entire thingamabob is a directed acyclic graph – or in this case, basically a dependency tree.
- Each subprocess as a node in the graph.
- Edges point from processes outputting resources to processes requiring those resources.
- The topological ordering of the graph is the order in which the processes need to be complete.
This solution requires the toposort package for the heavy graph lifting.
