NAME
       last - indicate last logins of users and teletypes

SYNOPSIS
       last [ -N ] [ name ...  ] [ tty ...  ]

DESCRIPTION
       Last  will  look  back  in  the  wtmp file which records all logins and
       logouts for information about a user, a teletype or any group of  users
       and teletypes.  Arguments specify names of users or teletypes of inter‐
       est.  Names of teletypes may be given fully or abbreviated.  For  exam‐
       ple  ‘last  0’  is  the same as ‘last tty0’.  If multiple arguments are
       given, the information  which  applies  to  any  of  the  arguments  is
       printed.   For  example  ‘last root console’ would list all of "root’s"
       sessions as well as all sessions on the console  terminal.   Last  will
       print  the  sessions  of the specified users and teletypes, most recent
       first, indicating the times at which the session began, the duration of
       the  session, and the teletype which the session took place on.  If the
       session is still continuing or was cut short by a reboot, last so indi‐
       cates.

       The pseudo-user reboot logs in at reboots of the system, thus

            last reboot

       will give an indication of mean time between reboot.

       Last  with  no  arguments prints a record of all logins and logouts, in
       reverse order.  The -N option limits the report to N lines.

       If last is interrupted, it indicates how far the search has  progressed
       in  wtmp.  If interrupted with a quit signal (generated by a control-\)
       last indicates how far the search has progressed so far, and the search
       continues.
