Linux permissions help

Hi

I am a newbie and trying to figure out how the file permisions work:

I see Each file has a set of 3 permissions:

Access permissions
-Owner
-Group
-Others
Ownership
-User
-Group

and
Advanced permissions:
Class    show entries   write entries   enter    special
User      x                   x                    x
Group    x                   x
Others   x                                         x         x

and so on, please could someone explain this to me or point me to a good article on the permissions.

thx

Hi iqula,
This article is a good description of the basic file permissions:-
http://www.freeos.com/articles/3127/

The 'chmod' manual page (man chmod) also gives some usefull information.

That clears things up a bit, are there any articles regarding setting up the filesystem so that I can lock it and the apps up as much as possible for a group of terminal users, ie an example setup?

I am not aware of any examples but Linux has always been a multi user system so the default permissions stop normal users from doing things they shouldn't. The only time you need to worry about things is if you need to give people extra permissions or enable them to run specific programs.
