How To Navigate Inside A Directory/Folder In Linux Without CD Command? 如何在 Linux 中不使用 CD 命令进入目录/文件夹？
====== ======
As everybody know that we can’t navigate inside a directory in Linux without CD command. 众所周知，如果没有 CD 命令，我们无法 Linux 中切换目录。
Yes that’s true but we have the Linux built-in command called `shopt` that help us to solve this issue. 这个没错，但我们有一个名为 `shopt` 的 Linux 内置命令能帮助我们解决这个问题。
[shopt][1] is a shell builtin command to set and unset various bash shell options, which is installed so, we no need to install it again. [shopt][1] 是一个 shell 内置命令，用于设置和取消设置各种 bash shell 选项，由于它已安装，因此我们不需要再次安装它。
Yes we can navigate inside a directory without CD command after enabling this option. 是的，我们可以在启用此选项后，可以不使用 CD 命令切换目录。
We will show you, how to do this in this article. This is a small tweak but it’s very useful for newbies who all are moving from Windows to Linux. 我们将在本文中向你展示如何操作。这是一个小的调整，但对于那些从 Windows 迁移到 Linux 的新手来说非常有用。
This is not useful for Linux administrator because we won’t navigate to the directory without CD command, as we had a good practices on this. 这对 Linux 管理员没用，因为我们不会在没有 CD 命令的情况下切换到该目录，因为我们对此有一个很好的做法。
If you are trying to navigate a directory/folder in Linux without cd command, you will be getting the following error message. This is common in Linux. 如果你尝试在没有 cd 命令的情况下切换 Linux 的目录/文件夹，你将看到以下错误消息。这在 Linux 中很常见。

To achieve this, we need to append the following values in a user `.bashrc` file. 为此，我们需要在用户 `.bashrc` 中追加以下值。
### What Is the .bashrc File? ### 什么是 .bashrc ？
The “.bashrc” file is a shell script which is run every time a user opens a new shell in interactive mode. “.bashrc” 是一个 shell 脚本，每次用户以交互模式打开新 shell 时都会运行该脚本。
You can add any command in that file that you want to type at the command prompt. 你可以在该文件中添加要在命令提示符下输入的任何命令。
The .bashrc file itself contains a series of configurations for the terminal session. This includes setting up or enabling: colouring, completion, the shell history, command aliases and more. .bashrc 文件本身包含终端会话的一系列配置。包括设置和启用：着色、补全，shell 历史，命令别名等。
