- ...files.
- If you have ``r'' and not ``x'' on a directory
you have permission to list the directory, but not to access
its files.
- ...permissions,
- The superuser can also change the
ownership of a file by using the chown command. There are
also several ``special'' permissions that haven't been listed here.
For more information, see the
chown and chmod manual pages.

- ...includes
- These are
not real lists of users, but they behave as if they were.
- ...locally
- It does not include users whose
authentication originated outside of MIT (e.g., CMU). Reciprocally,
for files at CMU, it doesn't include users from MIT...
- ...cp
- Read the manual
pages.
- ...space
- Actually, some NFS filesystems on Athena
do have group quotas.
A group quota would say something like ``Users
in group a are allowed to store b blocks of data on disk
c.'' This works better than regular user quotas, but it still
has its share of problems.
- ...commands
- Many AFS commands are of this type, i.e., a
suite of related commands rather than many distinct commands.
- ...lists
- The exceptions are specifically
``hidden'' system lists.
- ...cell
- To authenticate with a non-MIT cell, you need
to have an account there. World-readable files are accessible without
authentication.
- ...tickets
- For more information about Kerberos, see
An
Inessential Guide to Athena, available from SIPB.
- ...rs_aix31
- The values of
@sys for various Athena machines can be found in the file
/afs/athena/service/systypes.

- ...information
- Older users will often point this fact out
to the less experienced ones by using a word of sage advice, ``RTFM'',
which stands for ``Read The Friendly Manual''.
- ...command
- Further information can be found in the manpage for the
apropos command.
