cd /path/to/directory && ( find . -type d | LC_ALL=C sort; find . -type f -exec md5sum {} + | LC_ALL=C sort -k 2 ) | md5sum; cd - > /dev/null


# Where: the command:
#   - finds all directories located under /path/to/directory location,
#   - finds all regular files located under /path/to/directory location and computes MD5 sums for them,
#   - computes and prints final MD5 sum for directories and regular files


# Example output:
