last(1)                                                   last(1)



     NAME
          last - display login and logout times for each user  of  the
          system

     SYNOPSIS
          last [name ...]  [tty ...]

     DESCRIPTION
          last will look back in the wtmp file which records all lo-
          gins and logouts for information about a user, a terminal or
          any group of users and terminals.  Arguments specify names
          of users or terminals of interest.  Names of terminals may
          be given fully or abbreviated.  For example, last 0 is the
          same as last tty0.  If multiple arguments are given, the in-
          formation 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 reports the sessions of the specified users and termi-
          nals, most recent first, indicating start times, duration,
          and terminal for each. If the session is still continuing or
          was cut short by a reboot, last so indicates.

     EXAMPLES
               last reboot

          will give an indication of mean time between reboots of the
          system.

          last with no arguments prints a record of all logins and lo-
          gouts, in reverse order.  Since last can generate a great
          deal of output, piping it through the more program for
          screen viewing is advised.

          If last is interrupted with an Interrupt signal, (generated
          by CONTROL-C) it indicates how far the search has progressed
          in wtmp.  If interrupted with a quit signal (generated by a
          CONTROL-\), last exits and dumps core.

          CONTROL-D (EOF) signal does nothing.  Therefore exit grace-
          fully from last with an interrupt signal.
