You can manage groups using either shell commands or GUI utilities Groups are an effective way to manage access and permissions, letting you control several users with just their group name
/etc/group and /etc/gshadow
The system file that holds group entries is called /etc/group The file consists of group records, with one record per line and its fields separated by colons A group record has four fields: a group name, a password, its ID, and the users who are part of this group The Password field can be left blank The fields for a group record are as follows: Group name The name of the group, which must be unique
Password With shadow security implemented, this field is an x, with the password indicated in the /etc/gshadow file
Part VII:
System Administration
Group ID
The number assigned by the system to identify this group
Users The list of users that belong to the group, separated by commas Here is an example of an entry in an /etc/group file The group is called engines, the password is managed by shadow security, the group ID is 100, and the users who are part of this group are chris, robert, valerie, and aleina:
engines:x:100:chris,robert,valerie,aleina
As in the case of the /etc/passwd file, it is best to change group entries using a group management utility like groupmod or groupadd All users have read access to the /etc/ group file With shadow security, secure group data such as passwords are kept in the /etc/ gshadow file, to which only the root user has access
User Private Groups
A new user can be assigned to a special group set up for just that user and given the user s name Thus the new user dylan is given a default group also called dylan The group dylan will also show up in the listing of groups This method of assigning default user groups is called the User Private Group (UPG) scheme The supplementary groups are additional groups that the user may want to belong to Traditionally, users were all assigned to one group named users that subjected all users to the group permission controls for the users group With UPG, each user has its own group, with its own group permissions
Group Directories
As with users, you can create a home directory for a group To do so, you simply create a directory for the group in the /home directory and change its home group to that group and allow access by any member of the group The following example creates a directory called engines and changes its group to the engines group:
