    LAST(1)             UNIX Programmer's Manual		  LAST(1)

    NAME
         last - indicate last logins of users and teletypes

    SYNOPSIS
         last [ -f filename ] [ -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 interest.  Names of teletypes
         may be given fully or abbreviated.  For example `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 ses-
         sion is still continuing 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 prints a record of all logins and
         logouts, in reverse order.  The -f filename option allows
         the user to examine an alternate wtmp file.  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 (gen-
         erated by a control-\) last indicates how far the search has
         progressed so far, and the search continues.
