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


NAME

     lastlogin -- indicate last login time of users


SYNOPSIS

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


DESCRIPTION

     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 regard-
     ing 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.)


FILES

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


EXAMPLES

     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
