Using grep invert function to compare two md5 hash lists

I’ve mounted two .dd images in Linux by using losetup and created a list of hash values for every file located on those images:

md5deep -r  -e * > winXPimage1.txtmd5deep -r  -e * > winXPimage2.txt

This is how both hash lists look like:

d41d8cd98f00b204e9800998ecf8427e  /media/74444E0F444DD510/AUTOEXEC.BAT17d7055859d99a0d606cfaf17ae38638  /media/74444E0F444DD510/boot.inid41d8cd98f00b204e9800998ecf8427e  /media/74444E0F444DD510/CONFIG.SYS88cf0ff92a4a9fa7bd9b7513b2e9e22b  /media/74444E0F444DD510/Documents and Settings/… Etc…

The two images contain windows XP installation files and standard programs. The second image, however, also contains a lot of pictures (jpg, png, etc.).

I want to use grep to compare the two hash lists that I’ve created and filter out all the hashes related to the .jpg files from the second image.

I've used the following command to remove all the unnecessary information from the first image:

cut -f 1 -d '' winXPimage1.txt > winXPimage1New.txt

So now the image1 hash list looks like this:

d41d8cd98f00b204e9800998ecf8427e17d7055859d99a0d606cfaf17ae38638d41d8cd98f00b204e9800998ecf8427eetc…

I’m trying to use grep invert command to compare winXPimage1New.txt with winXPimage2.txt (contains jpeg hash values) and display all the non-matching jpg hash lines:

grep -v -f winXPimage1New.txt winXPimage2.txt/*.jpggrep -v -f .*[.jpg] winXPimage1New.txt winXPimage2.txt

None of these commands return jpg hash values from the second image hash list. I’m just not sure where exactly do I have to put the .jpg file extension as I’m very new to Linux in general.
