说明
/etc/group is the system file that defines groups and their members. Each line contains a group entry with four colon-separated fields: group name, password placeholder, numeric GID, and a comma-separated list of member usernames. Groups control file access permissions and are fundamental to Unix security. Users can belong to multiple groups, with one primary group set in /etc/passwd.
