If you’re working with files in the Terminal and switching back and forth between two directories, we’re about to save you some time. There is a shortcut command that allows you to toggle between two directories on the command line.

如果您正在终端中处理文件并在两个目录之间来回切换，我们将为您节省一些时间。 有一个快捷命令，可让您在命令行的两个目录之间切换。

First, as usual, change to your first directory by typing the following command at the prompt and pressing Enter.

首先，像往常一样，在提示符下键入以下命令并按Enter键，以转到第一个目录。

cd First/Directory/

Where `First/Directory/` is name of the directory you want to change to.

其中`First/Directory/`是要更改到的目录的名称。

You can also [use tab completion][] to enter the directory name by typing a few characters in the name and then pressing Tab to finish entering the name.

您也可以[使用制表符完成功能][use tab completion]来输入目录名称，方法是在名称中键入几个字符，然后按Tab键完成输入名称。

Now, we want to switch to a second directory, so we use the cd command and tab completion again.

现在，我们要切换到第二个目录，因此我们使用cd命令并再次使用制表符补全。

![02\_changing\_to\_second\_directory][02_changing_to_second_directory]

Now, instead of typing the first directory name to go back to that directory, you can type the following command at the prompt and press Enter.

现在，您无需键入第一个目录名称即可返回该目录，而可以在提示符下键入以下命令，然后按Enter键。

cd -

That’s simply the `cd` command followed by a space and then a dash. The name of the directory you’re toggling to displays and then you’re taken to that directory.

那只是`cd`命令，后跟一个空格，然后是一个破折号。 您要切换到的目录名称将显示，然后将您带到该目录。

![03\_changing\_back\_to\_first\_directory][03_changing_back_to_first_directory]

To toggle back to the second directory again, use the `cd -` command again.

要再次切换回第二个目录，请再次使用`cd -`命令。

![04\_changing\_back\_to\_second\_directory][04_changing_back_to_second_directory]

You can also press the up arrow key once to access the last command used from the command line history, which in this case was `cd -`. So, at this point, to toggle back and forth between these two directories, all you do it press the up arrow key and Enter. That’s quicker than typing out the path each time, even when you use tab completion.

您也可以按一次向上箭头键，以访问命令行历史记录中使用的最后一条命令，在本例中为`cd -` 。 因此，此时，要在这两个目录之间来回切换，只需按向上箭头键和Enter键即可。 这比每次键入路径都更快，即使您使用制表符补全也是如此。
