Does using "rm" command cause journaling corruption?
NOTE FOR CASUAL READERS: rm -rf destroys data.  Use with caution.


rm -rf may appear to go fast, but it is actually recursively going depth-first into each directory and unlinking the files within—the same operation that is used for any file deletion on Unix systems.

You can see how rm -rf works by adding the -v flag, e.g. rm -rfv.

There's no reason to believe that rm itself is responsible for journaling failures.  It's a proven and safe command that does not have any low-level access to the disk.

It is possible that the access pattern created triggered some bug in HFS+, but that seems unlikely as well; I rm -rf sizable trees of files on my machine frequently and haven't seen a problem.
