什么是路径//,它与/有何不同

linux

我们知道根目录是/,根据posix,还有另一个目录//与/不同。当使用ls /和ls //时,输出与stat相同,但是,如果cd /和cd
//则输出不同,尽管目录内容相同。那真的让我感到困惑。有人得到答案了吗?

E10) Why does `cd //' leave $PWD as `//'?

POSIX.2, in its description of `cd', says that *three* or more leading
slashes may be replaced with a single slash when canonicalizing the
current working directory.

This is, I presume, for historical compatibility.  Certain versions of
Unix, and early network file systems, used paths of the form
//hostname/path to access `path' on server `hostname'.
