LAST(1)                     General Commands Manual                    LAST(1)



NAME
       last - indicate last logins by user or terminal

SYNOPSIS
       last [ -number ][ -f filename ] [ name...  ] [ tty...  ]


DESCRIPTION
       last  looks  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 interest.
       Names of teletypes may be given fully or abbreviated.  For example last
       0 is the same as lasttty0.  If multiple arguments are given, the infor-
       mation 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 displays 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  tele-
       type which the session took place on.  If the session is still continu-
       ing or was cut short by a reboot, last so indicates.

       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 displays a record of all logins and logouts,  in
       reverse order.

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

OPTIONS
       -number
              limit the number of entries displayed to that specified by  num-
              ber.

       -f filename
              Use  filename  as  the  name  of  the accounting file instead of
              /var/adm/wtmp.
