NAME
group
- format of the group permissions file
DESCRIPTION
The file
Aq Pa /etc/group
consists of newline separated
ASCII
records, one per group, containing four colon
`:'
separated fields. These fields are as follows:
- group
-
Name of the group.
- passwd
-
Group's
encrypted
password.
- gid
-
The group's decimal ID.
- member
-
Group members.
The
group
field is the group name used for granting file access to users
who are members of the group.
The
gid
field is the number associated with the group name.
They should both be unique across the system (and often
across a group of systems) since they control file access.
The
passwd
field
is an optional
encrypted
password.
This field is rarely used
and an asterisk is normally placed in it rather than leaving it blank.
The
member
field contains the names of users granted the priviledges of
group
The member names are separated by commas with out spaces or newlines.
A user is automatically in a group if that group was specified
in their
/etc/passwd
entry and does not need to be added to that group in the
/etc/group file.
