Re: old burned cd file in wav

I like to do a recursive md5sum (or sha256sum):

find * -name *.flac -exec md5sum {} ; > flacmd5_20201001.txt

The resulting file is portable. I can take it to any mirror of my music 
and use "md5sum -c flacmd5_20201001.txt" to verify that mirror is 
identical to the other. An added bonus is that it's a snapshot in time 
so I can verify that the files are the same today as they were last year.
