Take a look at "diff" - it provides an option "-r" that traverses
subdirectories. So if you use "diff -rsq <location of the directory on
the mounted dvd> <location of the directory on disk>", you will get a
list of files that only exist on one or the other side, that are
identical or which files differ (without showing the difference). This
list could then be piped into "grep" with some clever patterns and then
be fed into "rm" to delete them (gotta love Unix). Example:
$ find .
.
./A
./A/fileC
./A/fileA
./A/fileD
./A/fileB
./B
./B/fileC
./B/fileA
./B/fileB
$ diff -rsq A B
Files A/fileA and B/fileA are identical
Files A/fileB and B/fileB differ
Files A/fileC and B/fileC are identical
Only in A: fileD
$ diff -rsq A B | grep "are identical"
Files A/fileA and B/fileA are identical
Files A/fileC and B/fileC are identical
$ diff -rsq A B | grep "are identical" | cut -f2 -d" "
A/fileA
A/fileC
(this of course assumes that file names don't include spaces, otherwise
you may have to come up with a more elaborate script.
Also, the "samefile" utility might come in handy, it compares files and
detects duplicates, even if they have a different name. You can get a
package from my home:LenzGr repository on the openSUSE build service.
Bye,
LenZ
