man page of group

group: user group file

group - user group file


/etc/group is a text file which defines the groups on the system. There is one entry per line, with the following format: group_name:password:GID:user_list The field descriptions are: group_name the name of the group. password the (encrypted) group password. If this field is empty, no password is needed. GID the numerical group ID. user_list a list of the usernames that are members of this group, separated by commas.




As the 4.2BSD initgroups(3) man page says: No-one seems to keep /etc/group up-to-date.
