How to generate a valid MD5SUMS file

The default OSX md5 -r command doesn't generate a valid format:

$ md5 -r LICENSE
95baec3fa8136f631e8b7bad5460d7b6 LICENSE
# It should output:
95baec3fa8136f631e8b7bad5460d7b6  LICENSE

In order to fix this, you can extends the md5 this way:

$ md5 -r LICENSE | sed 's/ /  /'
95baec3fa8136f631e8b7bad5460d7b6  LICENSE

If you need to generate a valid MD5SUMS format for many files in one command:

$ find . -not -empty -type f -d 1 | \
xargs -I %s basename %s | xargs -I %s md5 -r %s | sed 's/ /  /'
95baec3fa8136f631e8b7bad5460d7b6  LICENSE
