When I realized that I did not have permission to access to the /root
user's home directory, I followed the advice from this post which was to execute the command sudo -i
(which I did) and then afterwards I executed the command sudo chmod -R 777 /root
(which isn't the root of the file system).
With that being said, I wanted to revert my command sudo chmod -R 777 /root
and sudo -i
(whatever this one did...) to the previous and default permission (whatever that is) so I then executed the command sudo chmod -R 755 /root
. Is the latter command the correct one to execute?
Thank you for your answers!
sudo -i
didn't really do anything in this context. Howeversudo chmod -R 755 /root
doesn't really reverse your earlier command - in particular, it will leave any plain files unde/root
with execute permission. Unfortunately there's no magic command to undo a recursivechmod
