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
17              the name of the group.
18
19       password
20              the (encrypted) group password.  If  this  field  is  empty,  no
21              password is needed.
22
23       GID    the numeric group ID.
24
25       user_list
26              a  list  of  the usernames that are members of this group, sepa‐
27              rated by commas.
