What we're doing here is we're getting the output of the PWD command, which is just printing the present working directory where we are right now.

我们在这里所做的是获取 PWD 命令的输出，该输出只是打印我们现在所在的当前工作目录。

So maybe we want to include where the working directory that we are is in, and that's telling us the same information that we had in the other shell.

因此，也许我们想要包含我们所在的工作目录，这告诉我们与其他 shell 中相同的信息。
