* The -R option deletes the directory and any content under it recursively.
* The -r option is equivalent to -R.
* The -skipTrash option will bypass trash, if enabled, and delete the specified file(s) immediately. This can be useful when it is necessary to delete files from an over-quota directory.
+* The -safely option will require safety confirmation before deleting directory with total number of files greater than `hadoop.shell.delete.limit.num.files` (in core-site.xml, default: 100). It can be used with -skipTrash to prevent accidental deletion of large directories. Delay is expected when walking over large directory recursively to count the number of files to be deleted before the confirmation.
