Sorry about that. file1 is a list of numbers that need to be deleted or added. file2 is a list of current numbers and corresponding information. I want file3 to be just the "D," along with the first column of file2 associated with the number marked for deletion in file1.

I tried the script Franklin posted, but I got "syntax error near line 2". I forgot to mention I'm using Solaris 8 if that makes a difference. Thanks.
