DESCRIPTION

9       The  /etc/group file is a text file that defines the groups on the sys‐
10       tem.  There is one entry per line, with the following format:
11
12           group_name:password:GID:user_list
13
14       The fields are as follows:
15
16       group_name  the name of the group.
17
18       password    the (encrypted) group password.  If this field is empty, no
19                   password is needed.
20
21       GID         the numeric group ID.
22
23       user_list   a  list  of  the  usernames that are members of this group,
24                   separated by commas.
