User Commands                                             last(1)



NAME
     last - display login and logout information about users  and
     terminals

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


DESCRIPTION
     The last command looks in  the  /var/adm/wtmpx  file,  which
     records  all  logins  and  logouts,  for information about a
     user, a terminal, or any group of users and terminals. Argu-
     ments  specify  names  of users or terminals of interest. If
     multiple arguments are given, the information applicable  to
     any of the arguments is printed. For example, last root con-
     sole 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 on which the session  took  place.
     last also indicates whether the session is continuing or was
     cut short by a reboot.


     The pseudo-user reboot logs in when the system  is  shutdown
     and when it reboots. Thus,

       last reboot




     gives an approximate record of  when  the  operating  system
     instance was shutdown and when it rebooted. This can be used
     to calculate the availability of the operating  system  over
     time.


     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/wtmpx.  If  interrupted with a quit
     signal (generated by a CTRL-\), last indicates how  far  the
     search has progressed, and then continues the search.
