Hi,
Richard Owlett
I used "linux tutorial chmod chattr" [w/o quotes] in both DuckDuckGo
and Google.
A general search topic would be "linux file permissions" and "chattr".
I did a DuckDuckGo search adding "tutorial" and got what I had been
aiming at with my original searches. Thanks.
I can show you an example shell session on an ext4 filesystem.
I create a directory with a file and take away w-permissions:
$ cd /home/thomas/test
$ mkdir my_private_dir
$ echo private_content >my_private_dir/my_private_file
$ chmod a-w my_private_dir/my_private_file
$ chmod a-w my_private_dir
Now normal users including myelf cannot change the file content and
cannot rename or remove the file
That is my goal. I think doing all but the last step, examining the
result, doing the last step, examining that result, and examining the
differences will be educational. I suspect there is an AHAAA moment in
my future :}
I've not yet gone deeply enough in the material I've been given.
I believe I have a homework assignment. Retirement does create
opportunities.

I can of course not comment on what particular GUI tools do when they
promise the user to make something "Read-only".
(... or what systemd is willing to do for its clients ....)
Understood. You might add "How it will be interpreted by a Windows
refugee :/
Thanks again.
Have a nice day :)
