gid The group's decimal ID.
The _
\bg_
\br_
\bo_
\bu_
\bp field is the group name used for granting file access to users
who are members of the group. The _
\bg_
\bi_
\bd 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
_

\bw_
\bd field is an optional _

used and an asterisk is normally placed in it rather than leaving it
blank. The _

iledges of _

spaces or newlines. A user is automatically in a group if that group was
