It will find matching blocks at arbitrary byte offsets. Think of the original file as a sequence of fixed sized blocks. Inserting or deleting a single byte "breaks" that block so it no longer matches, but rsync will match all the blocks before and after that non-matching block. Note that one think that can break rsync for text files is MSDOS CR/LF vs Unix LF line termination. This effectively makes a change every line, and unless you have lines longer than the block size you are using, rsync will not be able to find a single match. -- Donovan Baarda <[EMAIL PROTECTED]> http://minkirri.apana.org.au/~abo/ -- To unsubscribe or change options: http://lists.samba.org/mailman/listinfo/rsync Before posting, read: http://www.catb.org/~esr/faqs/smart-questions.html
