I started off with changing to the folder I want to change permissions for, and that is the opt folder.
$ cd /opt/ test@testVM:/opt$
So I tried changing the permissions for this folder now using:
sudo chmod 775
And that hasn't worked. It showed this message:
Try 'chmod --help' for more information.
There is something I am forgetting or leaving out.
Please can you show me what I am doing wrong?
Thanks in advance.
