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  reboots.
     Thus,

          last reboot

     will give an indication of mean time between reboots.

     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.

OPTIONS

     The following options are supported:

     -a    Displays the hostname in the last column.

     -f filename
           Uses filename as  the  name  of  the  accounting  file
           instead of /var/adm/wtmpx.

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