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 num:name:leader:members where num is a decimal integer, name and leader are print- able 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 num in a line is a number used internally by a file server; there should be no duplicate nums in the file. A negative num is special: a user with a negative num cannot attach to the file server. The file /adm/users itself is owned by user adm, having a negative num, and write pro- tected to others, so it can only be changed via console com- mands.
