last(1)                                                             last(1)

NAME
     last - indicate last user or terminal login

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

DESCRIPTION
     last can be used to list the times when users have logged in and out.

OPTIONS
     No option specified:
          last lists all the login and logout times recorded in
          /var/adm/wtmpx and issues a message of the form "wtmpx begins
          date", indicating the date of the oldest entry.

     [n] number
          Limit the number of login and logout times displayed to number.

     -number
     -n number
          Limit the number of login and logout times displayed to number,
          but without printing the "wtmpx begins date" message.

     -f filename
          Specifies filename as the accounting file from which login and
          logout times are read. The default accounting file is
          /var/adm/wtmpx.

     name One or more login names and/or terminal numbers (tty???).

   Mode of operation

     The file /var/adm/wtmpx maintains a record of all login and logout
     times. last retrieves all the information about a user and the associ-
     ated terminals from this file.

     The arguments to last specify the login names or terminals for which
     information is to be retrieved. The names of terminals must be given
     in full.

     last displays the following information:

     -  the login name

     -  the terminal

     -  where appropriate, the name of the host from which the user logged
        in

     -  the login and logout times

last(1)                                                             last(1)

     By default, last displays a record of all logins and logouts in
     reverse order. If specific users or terminals are supplied as argu-
     ments, only the information for the selected users or terminals will
     be output. If multiple arguments are given, the information which
     applies to each individual argument is printed.

     last also indicates if the session is still continuing or was cut
     short by a reboot. The pseudo user reboot logs in each time the system
     is rebooted.

     If last is interrupted, it prints a message on the standard output to
     indicate how far the search had progressed until the time of the
     interrupt. If last is interrupted with SIGQUIT (CTRL-\), however, it
     will write the same message to standard output and then continue the
     search.

LOCALE
     The LCMESSAGES environment variable governs the language in which
     message texts are displayed. If LCMESSAGES is undefined or is defined
     as the null string, it defaults to the value of LANG. If LANG is like-
     wise undefined or null, the system acts as if it were not internation-
     alized.

     The LCALL environment variable governs the entire locale. LCALL
     takes precedence over all the other environment variables which affect
     internationalization.

EXAMPLES
     User Jon wishes to determine the last three times at which he logged
     in at terminal tty006. He also wishes to know if other users have been
     working at the same terminal.

     $ last -3 Jon tty006
     Jon   tty006              Fri  Aug   3   13:37 - 15:53  (02:15)
     Jon   tty006              Thu  Aug   2   10:25 - 12:56  (02:31)
     Jon   tty006              Wed  Aug   1   09:54 - 11:47  (01:53)
