Do a sha256sum of an entire directory name directory and check for integrity.
Modifying the IFS variable is necessary for filename with space.

$ IFS=' ' $ for i in $(find directory -type f -print);do sha256sum "$i";done > directory.SHA256SUM $ sha256sum -c directory.SHA256SUM

Kevin GroverThis handles spaces, does not need IFS set.
find directory -type f -print0 | xargs -0 sha256sum > directory.SHA256SUM
find directory -type f -print0 | xargs -0 sha256sum > directory.SHA256SUM

to generate recursively:
find . -type f -exec sha512sum {} \; > sha512sum-${PWD##*/}
to check:
sha512sum -c sha512sum-${PWD##*/} | grep -i fail
ps.: "${PWD##*/}" is only the directory name, like: "pwd | rev | cut -d / -f1 | rev"

# find directory -type f -exec sha256sum {} \; > directory.SHA256SUM
# sha256sum -c directory.SHA256SUM
Just to save some typing ;-)
BTW.: For bigger dirs using xargs might save more time.
