group file
From the original Amiga UNIX 2.1 manual. Some things it mentions may not be in this release.
With the amxbase package (with every 1.1 install), see group(4) instead.
NAME
group - group file
DESCRIPTION
The file /etc/group contains for each group the following information:
group name encrypted password numerical group ID comma-separated list of all users allowed in the group
group is an ASCII file. The fields are separated by colons; each group is separated from the next by a new-line.
Because of the encrypted passwords, the group file can and does have general read permission and can be used, for example, to map numerical group ID's to names.
During user identification and authentication, the supplementary group access list is initialized sequentially from information in this file. If a user is in more groups than the system is configured for, {NGROUPS_MAX}, a warning will be given and subsequent group specifications will be ignored.
