+## Use -print0/--null/-0 or -exec + to allow for non-alphanumeric filenames.
+
+### Problematic code:
+
+    find . -type f | xargs md5sum
+
+### Correct code:
+
+    find . -type f -print0 | xargs -0 md5sum
+
+### Rationale:
+
+By default, `xargs` interprets spaces and quotes in an unsafe and unexpected way. Whenever it's used, it should be used with `-0` or `--null` to split on `\0` bytes, and `find` should be made to output `\0` separated filenames.
+
+### Contraindications
+
+None.
