+For each of the directories, generate a digest file:
+<code bash>
+find DIR -type f -exec shasum {} + | LC_ALL=C sort -d -k 2 > shasums.txt
+</code>
+It's important to use ''LC_ALL=C'' and the option ''-d'' of ''sort'', to get compareable results on different machines.
+After that, you can diff the two shasums.txt:
+<code bash>
+diff shasums1.txt shasums2.txt
+</code>
+Or you use Meld as graphical diff tool:
+<code bash>
+meld shasums1.txt shasums2.txt
