last(1)            UNIX System V(User Environment Utilities)            last(1)


NAME
      last - indicate last user or terminal logins

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

DESCRIPTION
      The last command looks in the /var/adm/wtmp, file which records all
      logins 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 10 is the same as last term/10.  If multiple arguments are
      given, the information which applies to any of the arguments is printed.
      For example last root console lists all of root's sessions as well as all
      sessions on the console terminal.  last displays the sessions of the
      specified users and terminals, most recent first, indicating the times at
      which the session began, the duration of the session, and the terminal
      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, 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
      /var/adm/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.

      The following options are available:

     -n number|-number
                  Limit the number of entries displayed to that specified by
                  number.  These options are identical; the -number option is
                  provided as a transition tool only and will be removed in
                  future releases.

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