通过符号链接的路径歧义

Question

我注意到UNIX系统中有一个奇怪的行为：

I'm standing in /noob/

I have a symbolic link to a folder (A@ -> /B/C/D/A)

I enter the folder via my symlink (cd A) 

pwd says /noob/A/

In /B/C/D/A/ i have a file abc which I can see now.

I want to copy it to /noob/

I type cp abc ..

I type cd ..

I end up in /noob/ which is empty - but the file ended up in /B/C/D/ ???

当给定..作为参数时，关于cp和cd指向何处的歧义又如何呢？我感到困惑。谁能用我会理解的术语来解释它？（=简单）

祝一切顺利，请原谅UNIX-noob这个愚蠢的问题。拉瑟
