@SuperMild 求更。

送楼上某位一句话：人贵有自知之明。

@catror 「包」怎么也得是 packet 吧。

@feiyuanqiu bind 的过去式和过去分词都是 bound。

@stephenyin 你开心就好。

The execute permission grants the ability to execute a file. This permission must be set for executable programs, in order to allow the operating system to run them. When set for a directory, the execute permission is interpreted as the search permission: it grants the ability to access file contents and meta-information if its name is known, but not list files inside the directory, unless read is set also.
