Just today I found myself needing something like this.  Unfortunately
I ran into problems due to some of the file and directory names
containing spaces and other non alphanumeric characters which confused
md5sum.

Here's what worked for me:

find . -type f >| files.list
sed 's/^/"/' files.list | sed 's/$/"/' > files.list.quoted
cat files.list.quoted |xargs md5sum >| md5sum.out

Then run "md5sum --status -c md5sum.out" in the target directory.

The sed command puts quotation marks around all the file names and the
--status flag to md5sum tells it not to output anything other than
wether it was successful or not.
