The code says everything:
代码说明了一切：
max@serv$ chmod 777 .
Okay, it doesn't say everything.
好吧，它并没有说明一切。
In UNIX and Linux, the ability to remove a file is notdetermined by the access bits of that file. It is determined by the access bits of the directory which contains the file.
在 UNIX 和 Linux 中，删除文件的能力不取决于该文件的访问位。它由包含文件的目录的访问位决定。
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.
这样想——删除文件不会修改该文件。您没有写入文件，那么为什么文件上的“w”很重要？删除文件需要编辑指向该文件的目录，因此您需要在该目录上添加“w”。
