Where can you find local group information in a Linux system?

The file located at /etc/group is where local group information is stored in a Linux system. This file contains entries for each group, detailing the group name, password (if any), group ID (GID), and a list of users that belong to each group. This structure allows system administrators to manage group memberships and permissions effectively.

The other options do not serve this purpose. The /etc/passwd file is used for storing user account information, such as usernames and user IDs, rather than group information. The directories /var/groups and /usr/groups are not standard locations for group information in Linux and do not exist in typical installations. Thus, /etc/group is the definitive source for local group information on Linux systems.
