Ethernet device ‘not managed’ in network-manager
Couldn’t use ethernet because the device was ‘not managed’ according to
sudo nmcli dev set enp0s31f6 managed yes
/etc/NetworkManager/NetworkManager.conf helped (after the usual service restarts).
But creating an this empty file did:
sudo touch /etc/NetworkManager/conf.d/10-globally-managed-devices.conf
Python temporary directories
Memory lapse on my side, I thought
tempfile.gettempdir() returned a random temporary directory I can use. Nope, it returns the absolute address of
/tmp or its equivalent on that platform.
I was thinking about
tempfile.gettempdir(). There are also
tempfile.TemporaryDirectory(), which gets automatically removed after the context ends or the object is deleted.
It’s the kind of things I’m afraid of in shell scripts, where manually deleting a temporary directory could remove more than needed.
As usual, the python docu on topic 1 is a good thing to read.
Python pathlib removing directory tree
There’s no way to remove a directory with all its contents recursively using pathlib. 2
pathlib.rmdir() removes empty directories,
pathlib.unlink() removes files.
The way to do this is external libs, a la
Very very weird design decision, as removing stuff is in no way an uncommon operation.
But a recursive pathlib solution exists, from same StackOverflow answer:
from pathlib import Path def rmdir(directory): directory = Path(directory) for item in directory.iterdir(): if item.is_dir(): rmdir(item) else: item.unlink() directory.rmdir() rmdir(Path("dir/"))
