.SH DESCRIPTION
|
||
|
|
The permanent file servers each maintain a private list of users
|
||
|
|
and groups, in
|
||
|
|
.B /adm/users
|
||
|
|
by convention.
|
||
|
|
Each line in the file has the format
|
||
|
|
.IP
|
||
|
|
.IB id : name : leader :\fImembers\fP
|
||
|
|
.PP
|
||
|
|
where
|
||
|
|
.I name
|
||
|
|
and
|
||
|
|
.I leader
|
||
|
|
are printable strings excluding the characters
|
||
|
|
.LR ? ,
|
||
|
|
.LR = ,
|
||
|
|
.LR + ,
|
||
|
|
.LR - ,
|
||
|
|
.LR / ,
|
||
|
|
and
|
||
|
|
.LR : ,
|
||
|
|
and
|
||
|
|
.I members
|
||
|
|
is a comma-separated list of such strings.
|
||
|
|
Such a line defines a user and a group with the given
|
||
|
|
.IR name ;
|
||
|
|
the group has a group leader given by
|
||
|
|
.I leader
|
||
|
|
and group members given by the user names in
|
||
|
|
.IR members .
|
||
|
|
The
|
||
|
|
.I leader
|
||
|
|
field may be empty,
|
||
|
|
in which case any group member is a group leader.
|
||
|
|
The
|
||
|
|
.I members
|
||
|
|
field may be empty.
|
||
|
|
.PP
|
||
|
|
Lines beginning with
|
||
|
|
.L #
|
||
|
|
are ignored.
|
||
|
|
.PP
|
||
|
|
The
|
||
|
|
.I id
|
||
|
|
in a line is an identifier used in the on-disk structures maintained
|
||
|
|
by a file server; there should be no duplicate
|
||
|
|
.IR id s
|
||
|
|
in the file.
|
||
|
|
In older Plan 9 file servers,
|
||
|
|
.IR id s
|
||
|
|
are small decimal numbers.
|
||
|
|
In those,
|
||
|
|
a negative
|
||
|
|
.I id
|
||
|
|
is special: a user with a negative
|
||
|
|
.I id
|
||
|
|
cannot attach to the file server.
|
||
|
|
The file
|
||
|
|
.B /adm/users
|
||
|
|
itself is owned by user
|
||
|
|
.I adm
|
||
|
|
and write protected to others,
|
||
|
|
so it can only be changed via console commands.
