[SOLVED] File permissions issue

Hi there,

So, I have this Preferences file which I want it read-only for the app it belongs to, namely Edge. So, I chown-ed it to root:root and chmod-ed it to 444. Yet, Edge is able to delete it and recreate it.
My user is a sudoer, but sudo is configured to ask for password every time.

So how is that possible?

Thanks in advance.

Re: [SOLVED] File permissions issue

Deletign doesn't edit the file, but the directory (which is probably hopefully owned by your regular UID)
Set the file immutable, "chattr +i"

Re: [SOLVED] File permissions issue

the file is still able to be deleted even though its not able to be read or modified, you need to set it immutable using 'chattr +i' as root.

[EDIT] dammit, beaten to it

Re: [SOLVED] File permissions issue

Works like a charm. This file attributes stuff is completely new info for me. Thank you both.
