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 structures main‐
tained by a file server; there should be no duplicate ids in the file.
In older Plan 9 file servers, ids are small decimal numbers. In those,
a negative 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 com‐
mands.
