Like

 For directories, this overwrites contents without pruning them, so the resulting
 directory may have more files than have been copied.

Deletes the given file. Raises 
eISDIR8
 if run on a directory. Does not follow symbolic links.
Throws:
<00>  for wrong file type (directory)
<00> if the file does not exist
<00>  if the directory cannot be read<00>
ADeletes the given directory, which must be empty, never symlinks.
Throws:

<00># for wrong file type (regular file)
<00> if directory does not exist
<00> if directory is not empty
<00>. if we can't open or write to parent directory

Notes: calls rmdir<00>

PDeletes the given directory recursively. Does not follow symbolic
 links. Tries 
<00>/ first before attemtping a recursive
 deletion.

(On directory contents this behaves like 
<00>

 and thus will ignore any file type that is not

 In case of directory, performs recursive deletion. In case of
 a symlink, the symlink file is deleted.

dMove a file. This also works across devices by copy-delete fallback.
