last

NAME

       last -- indicate last logins by user or terminal

SYNOPSIS

       last [-number] [-f filename] [-t tty] [-h hostname] [-i
       address] [-l] [-y] [name...]

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.  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 displays the sessions of
       the specified users  and  teletypes,  most  recent  first,
       indicating the times at which the session began, the dura-
       tion 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 indicates.

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

       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
       last  indicates  how far the search has progressed so far,
       and the search continues.
