I'm using this right now:
time md5sum -c *.txt | pv | grep -v ': OK$'
but aren't there any smart solutions that can list that how many files haven't been checked? I mean I have many md5sum's in .txt files in a dir, and I need to check them, but it would be a good thing to know that how much files are left to scan..
p.s.: so it's not really a progress bar, just a counter that output how many files are there left to "md5sum -c FILENAME"..
