How do I correctly run scripts?

[MeesjeKeesie]

This may not be the correct place to ask this in, but I got it working with Linux and Ubuntu, but for research purposes, I need to run a script to send some data to another node. I've created the script (python file) but I've also get the warning that the disk is protected against writing, and I don't know how I can place it into my virtual enviroment. Is there someone who can help me, and give me a brief explanation on how the script command works?

The script I want to implement:

import subprocess
from datetime import datetime

#Contact and message
contact = "BC904423" / The contact I want to send a message to and is in my contact list
message = "Hello, this is a test message with timestamp"

#Exact Time (UTC or local time, dependand of my module, idk)
timestamp = datetime.now().strftime("%Y-%m-%d %H:%M:%S")

#Combine message and time
full_message = f"{message} @ {timestamp}"

#Serial Port
serial_port = "/dev/ttyUSB0"

#Building command
cmd = [
    "meshcli",
    "-s", serial_port,
    "msg", contact,
    full_message,
    "wa"  # wa = write and acknowledge
]

#Run
result = subprocess.run(cmd, capture_output=True, text=True)

#Show output
print("Sent:", full_message)
print("Result:", result.stdout)
print("Error:", result.stderr)

As a somewhat intermediate coder myself I think this code should be totally fine running, but it's just that I can't seem to upload it to my .venv and I really don't know where to place it.

I'm not really good with venvs, and I don't think a lot of people read meshcore-cli issues :/

I also think you can do without venvs ... if you install meshcore-cli with pipx install meshcore-cli, meshcli should be available as a command ... maybe it is not because ~/.local/bin is not in your PATH ?

I don't understand the part where you say your disk is write protected ? Is Ubuntu now using an inmutable file system ?

Thanks, I did not know it could work without a venv. Via Nautilus I can grant access to place files in my Ubuntu Disk. It was locked, but it should all work now. I hope I get it running. If not, I will try something else. Also do you guys have some kind of discord server where I can ask these types of questions? Or some other communication platform?

I got at least the scripts in my-scripts. The disk was protected against writing. But if I first put the file inside of an USB-stick, and got that usb-stick connected with ubuntu, I was able to transfer the files to the system, fortunatly. I will try to get the scripts running and update you! Thanks for the reply!
