摘录自

Excerpt from an interview with Ken Thompson (9-6-89):

每次我们建立目录时， 约定，我们把它放在另一个 目录称为目录- 目录，它是dd.它的名字是 dd和所有用户目录 实际上是大多数其他目录， 用户维护自己的目录 系统，指针指向dd，和 dd缩写为点号" ，然后 dd用于目录-目录.

Every time we made a directory, by convention we put it in another directory called directory - directory, which was dd. Its name was dd and that all the users directories and in fact most other directories, users maintain their own directory systems, had pointers back to dd, and dd got shortened into ‘dot-dot,’ and dd was for directory-directory.
