→File Permissions
'''NOTE:''' In this course, we cannot create groups or assign users to groups - you may learn how to do<Br>that if you take a Unix/Linux administration account.
On the other hand, you can changewhich '''user''',<br>which user, existing '''same group members ''' or existing '''other group members ''' can or cannot access a directory or regular file.
Permissions act like a two-layered defence: First, the directory that contains regular files, and second, to the regular files themselves.
