我如何删除这个文件？

How can I delete this file?

推荐答案

在code说的一切：

max@serv$ chmod 777 .

好吧，不说的一切。

Okay, it doesn't say everything.

在UNIX和Linux，删除文件的能力的不可以由该文件的存取位决定。它是由包含该文件的目录的访问位决定。

In UNIX and Linux, the ability to remove a file is not determined by the access bits of that file. It is determined by the access bits of the directory which contains the file.

它认为这种方式 - 删除文件不会修改文件。您没有写入该文件，因此该文件事为什么要W？删除文件需要编辑指向文件的目录，所以你需要在该目录中的W。

Think of it this way -- deleting a file doesn't modify that file. You aren't writing to the file, so why should "w" on the file matter? Deleting a file requires editing the directory that points to the file, so you need "w" on the that directory.
