You requested that there be only one line of output, and the code samples that you have been given provide a single line of output as you requested; so sort will have no affect.

If you would have answered the questions I asked in message #5 in this thread, the volunteers here trying to help you might be able to help you find a solution to your problem instead of trying to patch together something that probably still won't meet your needs.

Please answer the questions I asked earlier so we can help you find a solution will meet your needs.

LASTLOGIN(8)						    BSD 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 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.) 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 SEE ALSO
last(1), lastlog(5), lastlogx(5), ac(8) AUTHORS
John M. Vinopal wrote this program in January 1996 and contributed it to the NetBSD project. BSD
