Forgot to mention I am looking for a util for Win2000 or DOS.
PDFTK can do that, you can download it from

Copied from that page:
pdftk: the pdf toolkit
If PDF is electronic paper, then pdftk is an electronic staple-
remover, hole-punch, binder, secret-decoder-ring, and X-Ray-glasses.
Pdftk is a command-line tool for doing everyday things with PDF
documents. Keep one in the top drawer of your desktop and use it to:
* Merge PDF Documents
* Split PDF Pages into a New Document
* Decrypt Input as Necessary (Password Required)
* Encrypt Output as Desired
* Fill PDF Forms with FDF Data and/or Flatten Forms
* Apply a Background Watermark
* Report on PDF Metrics such as Metadata, Bookmarks, and Page
Labels
* Update PDF Metadata
* Attach Files to PDF Pages or the PDF Document
* Unpack PDF Attachments
* Burst a PDF Document into Single Pages
* Uncompress and Re-Compress Page Streams
* Repair Corrupted PDF (Where Possible)
Pdftk allows you to manipulate PDF easily and freely. It does not
require Acrobat, and it runs on Windows, Linux, Mac OS X, FreeBSD and
Solaris.
Pdftk is free software (GPL).
