Re: bug: rm command

As you haven't specified the operating system you are using the
question is impossible to answer.

From (coreutils)rm invocation:
`-d'
`--directory'
     Attempt to remove directories using the `unlink' function rather
     than the `rmdir' function, and don't require a directory to be
     empty before trying to unlink it.  This works only if you have
     appropriate privileges and if your operating system supports
     `unlink' for directories.  Because unlinking a directory causes
     any files in the deleted directory to become unreferenced, it is
     wise to `fsck' the filesystem after doing this. Note that this
     option will call `unlink' on the target with no additional checks,
     so may be useful for non-directories in cases where `stat' fails
     for the target.
