Most
.Nm
commands accept the following general arguments:
.Pp
.Bd -filled -offset indent -compact
.Op Fl cell Ar cellname
Specifies which AFS cell to use, if the default cell is not to be used.
.Pp
.Op Fl noauth
Specifies that
.Nm
should not try to authenticate the connection to the server.
This may be
useful with shell scripts, or if there is a problem with the AFS cell.
Note that the server will reject many commands if
.Fl noauth
is specified.

.Pp
.Ic fs connect
.Op Ar mode
.Bd -filled -offset indent -compact
Set or get connected mode, if a mode is specified, the cache manager will be

attempt is made to contact a fileserver-
.El
.Pp
Disconnected mode is very useful for machines that are not connected to
the network at all times, such as laptops.
Disconnected mode is to be considered very experimental at this stage.

.Ed
.Pp
.Ic fs setacl
.Bd -filled -offset indent -compact
Add an acl entry on a directory.
Each entry consists of two components:
a user or group and a character string describing the permissions granted
for that user or group.
These characters and the permission they represent are:
.Bl -tag -width Fl -compact
.It Cm r
read the files
.It Cm l
list the files
.It Cm i
insert new files
.It Cm d
delete files
.It Cm w
write (change) the files
.It Cm k
lock files
.It Cm a
administer the acl, that is, to change the acl
.El
.Pp
There are also a few convinience strings recognized by
.Ic fs setacl :
.Bl -tag -width Fl -compact
.It Cm none
removes all permissions.
.It Cm read
adds 'rl' permissions, which are suitable for a read-only directory.
.It Cm write
adds all permissions except 'a', that is, the user/group can read, write,
delete etc. but not change the acl of the directory.
.It Cm all
add all permissions.
.El
.Pp
Note that in AFS you set the permissions on a directory, and the permissions
of a file are those of their directory.
So, if you move a file from one
directory to another, you might change the permission of the file, as
the two directorys may have different permissions.
.Pp
Of the traditional
.Ux
permission bits only the user part is honored, and is used for any
user permissioned by the directorys acl.
The group and world permission bits are ignored, but they are stored.
