       lastlog - examine lastlog file


       lastlog [options]


       lastlog formats and prints the contents of the last login log
       /var/log/lastlog file. The
        login-name, port, and last login time will be printed. The default (no
       flags) causes lastlog entries to be printed, sorted by their order in


       The options which apply to the lastlog command are:

       -h, --help
              Print help message and exit.

       -t, --time DAYS
              Print the lastlog records more recent than DAYS.

       -u, --user LOGIN
              Print the lastlog record for user with specified LOGIN only.

       The -t flag overrides the use of -u.

       If the user has never logged in the message
        **Never logged in** will be displayed instead of the port and time.


       The lastlog file is a database which contains info on the last login of
       each user. You should not rotate it. It is a sparse file, so its size
       on the disk is much smaller than the one shown by ls -l (which can
       indicate a really big file if you have a high UID). You can display its
       real size with ls -s.

       Large gaps in uid numbers will cause the lastlog program to run longer
       with no output to the screen (i.e. if mmdf=800 and last uid=170,
       program will appear to hang as it processes uid 171-799).
