NetBSD 6.1.5 - man page for lastlogin (netbsd section 8)

LASTLOGIN(8)			   BSD System Manager's Manual			     LASTLOGIN(8)

     lastlogin -- indicate last login time of users

     lastlogin [-nrt] [-f filename] [-H hostsize] [-L linesize] [-N namesize] [user ...]

     lastlogin will list the last login session of specified users, or for all users by default.
     Each line of output contains the user name, the tty from which the session was conducted,
     any hostname, and the start time for the session.

     If multiple users are given, the session information for each user is printed in the order
     given on the command line.  Otherwise, information for all users is printed, sorted by uid.

     lastlogin differs from last(1) in that it only prints information regarding the very last
     login session.  The last login database is never turned over or deleted in standard usage.

     The following options are available:

     -f filename
	     Process input from filename.  If the file ends with an ``x'', then it is assumed
	     that it is a lastlogx(5) file, else it is assumed to be a lastlog(5) file.

     -H hostlen
	     Set the field width for host output to hostlen characters.

     -L linelen
	     Set the field width for line output to linelen characters.

     -N namelen
	     Set the field width for name output to namelen characters.

     -n      Attempt to print numeric host addresses.  This option is only supported with
	     lastlogx(5) format files.

     -r      Reverse the order of the sort.

     -t      Sort by last login time (most recent first.)

     /var/log/lastlogx	default last login database
     /var/log/lastlog	compatibility last login database

     lastlogin looks by default to the /var/log/lastlogx database, where some old programs that
     are not utmpx(5) aware might only write to /var/log/lastlog.  To look at the old database
     one can use:

	   lastlogin -f /var/log/lastlog

     last(1), lastlog(5), lastlogx(5), ac(8)

     John M. Vinopal wrote this program in January 1996 and contributed it to the NetBSD project.
