Hi.

Suppose this is in file p1:
Code:
#!/usr/bin/perl
eval 'exec /usr/bin/perl -S $0 ${1+"$@"}'
    if $running_under_some_shell;
			# this emulates #! processing on NIH machines.
			# (remove #! line above if indigestible)

eval '$'.$1.'$2;' while $ARGV[0] =~ /^([A-Za-z_0-9]+=)(.*)/ && shift;
			# process any FOO=bar switches

$, = ' ';		# set output field separator
$\ = "\n";		# set output record separator

line: while (<>) {
    chomp;	# strip record separator
    if ($. == ($.-$FNRbase)) {
	$a{$_}++;
	next line;
    }
    if (!$a{$_}) {
	print 'line' . ($.-$FNRbase) . $_;
    }
}
continue {
    $FNRbase = $. if eof;
}

then try running it on a sample of your data to be sure it seems to do the right thing. Supply file names as you did for nawk (or possibly with the order reversed).

The Solaris box I have seem to have omiited processor a2p which automates the work of converting awk to perl. This was done on:
Code:
OS, ker|rel, machine: Linux, 2.6.26-2-amd64, x86_64
Distribution        : Debian 5.0.8 (lenny, workstation) 
perl 5.10.0

Best wishes ... cheers, drl

	       --rs	       output record separator (default newline)
	       --fs	       output field separator (default colon)
	       --fields        comma separated list of fields to print (default all)
	       --undef	       string to print for NULL values (default empty)
	       --memofile      specifies unstandard name of attached memo file
	       --memosep       separator for dBase III dbt's (default x1ax1a)

	       --table	       output in nice table format (only available when

	       dbfdump -fields id,msg table.dbf

	       ssh user@host 'cat file.dbf.gz' | gunzip - | dbfdump -

DESCRIPTION

       Dbfdump prints to standard output the content of dbf files listed. By default, it prints all fields, separated by colons, one record on a
       line. The output record and column separators can be changed by switches on the command line. You can also ask only for some fields to be
       printed.

       The content of associated memo files (dbf, fpt) is printed for memo fields, unless you use the "--nomemo" option.

       You can specify reading the standard input by putting dash (-) instead of file name.
