sorry, I didn't explain my request more detail. you are right. actually, the whole line is identical if field #2 is identical.
My OS is Solaris/SunOS. I will put my OS infor next time.
Thank you again.
I'm always glad to have helped. With the sample data you provided, the following would also work:
Code:
/usr/xpg4/bin/awk '
BEGIN {	FS = OFS = ","
}
$1 == "D" {
	if($0 in a)
		next
	a[$0]
	printed++
}
$1 == "T" {
	$2 = printed
}
1' file.CSV

Please use this code if you want to delete identical lines. Please use the code in post #2 if you want to delete lines with duplicate field #2 values in lines. (In both cases, only when field #1 is "D".)
