NAME
     first - an adaptation of last to display  login  and  logout
     information about users and terminals


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


DESCRIPTION
     first is identical to last apart from the following changes:

         Expanded username column from 8 to 16 characters.

         Full  length  timestamps  for  both  logon  and  logoff,
         including year.

         Option to display timestamps as seconds from 1970  (UNIX
         epoch time) for easier processing.

         Large file support.

     These changes are intended to make first more convenient for
     processing long (old) wtmpx files.


     The first 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, first root
     console lists all of root's sessions, as well  as  all  ses-
     sions  on  the console terminal. first displays the sessions
     of the specified users and  terminals,  most  recent  first,
     indicating  the  times at which the session began, the dura-
     tion of the session, and the terminal on which  the  session
     took place. first also indicates whether the session is con-
     tinuing or was cut short by a reboot.


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

         first reboot




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

User Commands                                            first(1)



     to calculate the availability of the operating  system  over
     time.


     first with no arguments displays a record of all logins  and
     logouts, in reverse order.


     If first is interrupted, it indicates how far the search has
     progressed  in  /var/adm/wtmpx.  If  interrupted with a quit
     signal (generated by a CTRL-\), first 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 transition tool  only  and  is
                              removed in future releases.


     -u                       Displays  times  as  seconds   from
                              beginning   of   1970  (UNIX  epoch
                              time).


ENVIRONMENT VARIABLES
     Date and time format is based on  locale  specified  by  the
     LC_ALL,  LC_TIME,  or  LANG  environments,  in that order of
     priority.


FILES
     /var/adm/wtmpx    accounting file
