Manual pages sections
Almost all UNIX operating systems have voluminous documentation known as manual pages. Every page is a document. If one wants to read a page then the command man at a shell prompt will show the manual, for example, "man ftp". Pages are referred by using the notation "name(manual-section)", for example time(1).

NAME

group - user group file

DESCRIPTION

/etc/group is an ASCII file which defines the groups to which users belong. There is one entry per line, and each line has the format:

group_name:passwd: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

all the group member's user names, separated by commas.

FILES

/etc/group

BUGS

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

SEE ALSO
