USERS(6) USERS(6)
NAME
users - file server user list format
DESCRIPTION
The permanent file servers each maintain a private list of
users and groups, in /adm/users by convention. Each line in
the file has the format
id:name:leader:members
where name and leader are printable strings excluding the
characters `?', `=', `+', `-', `/', and `:', and members is
a comma-separated list of such strings. Such a line defines
a user and a group with the given name; the group has a
group leader given by leader and group members given by the
user names in members. The leader field may be empty, in
which case any group member is a group leader. The members
field may be empty.
Lines beginning with `#' are ignored.
The id in a line is an identifier used in the on-disk struc-
tures maintained by a file server; there should be no dupli-
cate ids in the file. In fossil(4), ids are arbitrary text
strings, typically the same as name. In older Plan 9 file
servers, ids are small decimal numbers. In those, a nega-
tive id is special: a user with a negative id cannot attach
to the file server. The file /adm/users itself is owned by
user adm and write protected to others, so it can only be
changed via console commands.
