Re: binary diff
There are a few of them, take a look for example at xdelta and bsdiff Ely On Thu, Apr 3, 2008 at 10:45 AM, Erez D [EMAIL PROTECTED] wrote: hi i am looking for something like 'diff' which can compare binary files and give a result other then just 'differ' or 'same' the same as what diff does for text files. i though of using xxd with a regular diff, but that doesn't help, as if there is one byte missing, all lines are shifted which means they are different textually, when they are not really. thanks, erez. = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
Re: binary diff
Erez - Perhaps you could first convert the binary files to text representation (od --address-radix none) and then preform the comparison in that dimension?

Re: binary diff
xxd's function is exactly to convert from binary into text. Try to convert your binary files using: xxd -p -c1 (works for me: xxd -v output is xxd V1.10 27oct98 by Juergen Weigert). I checked also how to do it using od. The following would work (my od --version is 5.97): od -v -w1 -ta --address-radix none or: od -v -w1 -tx1 --address-radix none --- Omer On Thu, 2008-04-03 at 11:37 +0300, Yaacov Fenster - System Engineering Troubleshooting and other stuff wrote: Erez - Perhaps you could first convert the binary files to text representation (od --address-radix none) and then preform the comparison in that dimension?

The more you know about the files, the better tool you can choose. I've had good experience with xdelta. IIRC, it works very similar to the way rsync transfers files, with an advantage to xdelta, since it works locally. Also, xdelta is available both for Windows and Linux, if that matters to you. --yuval signature.asc Description: This is a digitally signed message part.
