last(1)                          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. Arguments specify names of users or ter‐
       minals of interest. If multiple arguments are  given,  the  information
       applicable  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 on which the ses‐
       sion 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 avail‐
       ability 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.

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
                                specified by number. These options are identi‐
                                cal; the -number option is provided as a tran‐
                                sition tool only and may be removed in  a  fu‐
                                ture release.
