### Rationale: ### 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.

POSIX does not require find or xargs to support null terminators, so you can also use `find -exec +`.
