Notas do Editor
- #3: Levecomoquemdiz
- #11: The user must have write permission in the parent directory.
- #13: If the permissions of the file do not permit writing, and the standard input device is a terminal, the user is prompted(on the standard error output) for confirmation. The rm utility removes symbolic links, not the files referenced by the links.
- #19: If the permissions of the file do not permit writing, and the standard input device is a terminal, the user is prompted(on the standard error output) for confirmation. The rm utility removes symbolic links, not the files referenced by the links.
