Compare copies of a file with md5

diff <(md5sum| cut -d " " -f 1) <(md5sum /media/green/| cut -d " " -f 1);echo $?
I had the problem that the Md5 Sum of a file changed after copying it to my external disk. This unhandy command helped me to fix the problem.

What Others Think

hmm - shouldn't diff suffice for that? If you need a copy command that makes sure the new file is correct use: "rsync src_file dst_file"

Hey, you're right :). I thought that I can use diff only with plain text. Do you think I should remove the command?
