I am having trouble understanding aspects of file/directory permissions. I
know how to make file readable, writeable, etc., but am having trouble
with advanced aspects. For instance I once read that you can create a user
called backup and use it to backup the whole disk. The idea was to give
backup read-only access to the whole disk. How can you give a specific
user certain permissions on files? What exactly are groups used for?
Thanks,
