I need a Solaris solution to produce "last" output (run against wtmpx) that displays YEAR data as well as month, day & time. Standard "last" output does not include YEAR data. Can someone help? Thanks!

The following script may serve your needs.  It doesn't provide all the options of the 'last' command, but it wouldn't be too difficult to change it.

#!/usr/bin/perl
use strict;

my $template = "A32 A4 A32 l s s2 x2 l2 l x20 s A257 x";
my $recordsize = length(pack($template,()));
open WTMPX,"/var/adm/wtmpx" or die "Unable to open wtmpx:$!\n";

my $record;

while (read(WTMPX,$record,$recordsize)) {
  my ($ut_user,$ut_id,$ut_line,$ut_pid,$ut_type,$ut_e_termination,$ut_e_exit,$tv_sec,$tv_usec,$ut_session,$ut_syslen,$ut_host)= unpack($template,$record);
  printf("%-9s %10s %s\n",$ut_user, $ut_line, scalar localtime($tv_sec)) if ($ut_user =~ /^[a-z]/);
}

close WTMPX;

last command on Solaris systems doesn't report the year included in its records,

please have a look at the answer in http:Q_21890379.html  for workarounds.

I believe Tintin's answer solves my problem. Just one follow-up question please. Is Perl a standard piece of all Solaris releases now? I see it on Solaris 8 , 9 and Solaris 10 systems that I examined this morning. Not sure if we have any Solaris 7 systems around ... but we may ...

Thanks to Tintin and Vuzh for the response! I answered my own follow-up question. I found some doc that says "Starting with Solaris 8, perl5.00503 (or higher) is supplied with the operating system". Thanks again!!
