GROUP(5)                  386BSD Programmer's Manual                  GROUP(5)

NAME
     group - format of the group permissions file

DESCRIPTION
     The file </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 priv-
     iledges 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.

FILES
