I'd stick with Linux although this is a generic unix issue.
But getting into the many flavors and subtle differences between
*nix OS's can be confusing. Best to start with what you have.
"Running Linux" has always been a great book. An online option
is http://rute.sf.net

the fact is BSD and SystemV-ish unixes do some different things
with permission bits -- especially setuid,setgid, and sticky bits.
The canonical references is, of course, the man pages on the system
you're on.

An example of what I mean. This is from the Solaris -- an SVR4 based
unix -- manpage of chmod
                20#0 Set group ID on execution if # is 7, 5, 3,
                      or 1.

                      Enable mandatory locking if # is 6, 4, 2,
                      or 0.

                      For directories, files are created with BSD
                      semantics for propagation of the group ID.
                      With this option, files and subdirectories
                      created in the directory inherit the group
                      ID of the directory, rather than of the
                      current process. It may be cleared only by
                      using symbolic mode.

Both the OReilly sysadmin book and the "Essential System Administration"
book are excellent resources for this kind of thing. But they are
not newbie books.

I've been doing this for 7 years now and I can assure you that
hard things in the computing world -- be it Windows are *nix -- are
still hard. complext networking environments and cross-platform
file sharing is still and always will be a hard problem.
