File permissions in linux can be managed as follows: First, one must set up users and groups by using groupadd and useradd. Second, one must add the users to the groups/directories using usermod. Thirdly, one must use chmod to manage permissions on a given file or directory. As a note: its necessary to navigate to the correct directory in order to modify files. Use command "ls - l" to view current files in directory.
