LASTLOG(8)                                                          LASTLOG(8)

       lastlog - examine lastlog file

       lastlog [(-u|--user) login-name]
               [(-t|--time) days] [(-h|--help)]

       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 the numerical UID.

       -u, --user login-name will cause the lastlog record for
              login-name only to be printed

       -t, --time days will cause only the lastlogins more recent
              han fIdays to be printed

       -h, --help print a one-line help message and exit.

       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.

       /var/log/lastlog - lastlog logging file

       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,  pro-
       gram will appear to hang as it processes uid 171-799).
