Group Membership
Group Membership
Every user always belongs to an administrative group. Users can also belong to file-
sharing groups.
Administrative groups exist primarily to define and manage the user authentication
records for users on your system. An administrative group must have a group number
from 0 through 255. You are always a member of only one administrative group. Your
user name and user ID are based on the name and number of your administrative
group.
File-sharing groups provide a mechanism for allowing arbitrary sets of users to share
files, particularly in the OSS environment. In addition to your administrative group, you
can be a member of up 31 other groups for file-sharing purposes.
Administrative Groups
An administrative group consists of all users whose user names have the same group
name and whose user IDs have the corresponding group number. In the preceding
examples, ROBIN and PAT share the group name SALES and its group number 147.
Thus they are members of the same administrative group.
To list all users who have the same administrative group, enter a USERS command in
one of these forms:
USERS group-name.*
or
USERS group-number,*
For example, the following USERS command uses the group-name to list all users
whose administrative group is the SALES group. The user names appear in
alphabetical order:
4> USERS SALES.*
GROUP . USER I.D. # SECURITY DEFAULT VOLUMEID
SALES .ALICE 147,062 GGGG $PERSNL.ALICE
SALES .ALTHEA 147,039 NUNU $PERSNL.ALTHEA
SALES .AUDREY 147,011 AGGO $BRIDGE.RAM
.

.
SALES .TRACY 147,064 NONO $PERSNL.TRACY
SALES .USER 147,003 GGGG $PERSNL.APLTUSER
SALES .VERNA 147,045 CUCU $PERSNL.VERNA
This USERS command uses the group-ID to list the same information. The user IDs
(under I.D. #) appear in ascending order.
5> USERS 147,*
GROUP . USER I.D. # SECURITY DEFAULT VOLUMEID
