[lug] Testing CDs and ISO Images

[Dhruva B. Reddy]

I recently burned a data CD and some of the files did not make it on
there in their entirety, which I did not find out until after I had
deleted the ISO image and original files from my hard drive (^%&*(%).

To prevent this from happening again, I am looking for a way to compare
directory trees, something like 'cmp', but compares whole trees.  Is
there an easy way to do this?

Thanks,
Dhruva
