Do you want to continue? [Y/n] …请不要认为这是重复的。我在目录 /tmp/test/ 以及一些子文件夹中创建了一个 root 文件夹。我已经更改了所有用户和组的读写权限，包括 root。
$ sudo chmod -R 666 /tmp/test/
在发出
$ ls -l /tmp/test/
ls: cannot access '/tmp/test/db': Permission denied
ls: cannot access '/tmp/test/sp': Permission denied
total 0
d????????? ? ? ? ? ? db
d????????? ? ? ? ? ? sp
这样的消息时，我无法创建新文件或目录。
$ printf 'test' >/tmp/test/sp/test
bash: /tmp/test/sp/test: Permission denied 这对我来说听起来很困惑。
