Re: [LUNI] Hexedit Challenge

Wow -- you really like doing things the hard way!

Maybe you could use a hand trying to get that disc mounted instead?  What have you tried?

Have you tried something similar to the following?

# dd if=/dev/cdrom of=/tmp/jpgs.iso
# mount -t iso9660 -o loop /tmp/jpgs.iso /mnt/tmp

(make sure /mnt/tmp is created and empty first...)

Subject: [LUNI] Hexedit Challenge

I was given a DVD-R of JPEG's someone took of my band for me.
Unfortunately, I can't mount it on any of the machines in my house, I was
able to use dd to get the raw data into a file, and using hexedit I am
able to extract the data I need.

However there are 180+ images on this disk, so I need to figure out how to
extract the images via a script.

Known Factors:
Each image begins with the following sequence


and ends with the third occurence of


or the first occurence of

FF D9 00 00

What could I use to parse the file, and extract each image into it's own
