说明
lastlog reports the most recent login of all users or a specified user by reading /var/log/lastlog. Unlike last, it shows only one record per user representing their most recent login. The lastlog file is a sparse file indexed by UID, so it can appear large but doesn't consume much disk space. Users who have never logged in show "Never logged in".
