FUNDAMENTALS A Complete Guide for Beginners
The cd command in Linux is a very useful command for navigation. The word cd stands for change directory. This command is used for changing the current directory of the user. cd is not your usual command it’s a shell built-in. In this article, I will explain the cd command in Linux and show you some useful examples.
A. Description
As the command word cd stands for Change Directory, it is pretty clear that this command helps a user to change the directory. The cd will take the user from the current directory (current location) to a specified directory.
B. Syntax
The syntax for the cd command is pretty simple which is the command itself followed by some specific options and destination directory name.
cd [OPTION]... [DIRECTORY]C. Options
Many useful options are available for the cd command. I have listed some of the most used ones here. However, if you want to know more about options for the cd command you can always check the help page for the cd command. Remember man page doesn’t exist for the cd command.
help cdUseful Options
- -L: Force symbolic link to be followed. This option is used by default when no option is given.
- -P: Use a physical directory structure rather than using symbolic links.
- -e: When the -P is supplied if the current directory can’t be determined then exit with a non-zero status.
- -@: on systems that support it, present a file with extended attributes as a directory containing the file attributes.
NB: The options in Linux CLI(Command Line Interface) are all case-sensitive. So, be cautious while using them.
Practical Examples of the “cd” Command in Linux
The cd command in Linux is an easy-to-use command which is used to change directory. Some of the most useful applications of the cd command have been illustrated below. In this article, I have worked with the following directories, you can also download those directories if you want to work with the same files. I have used the Directories below.
Example 1: Change Directory to Root Directory Using the “cd” Command in Linux
To navigate into the Root directory you have to use the slash (/) symbol. This symbol specifies the root directory. Now follow the steps below to see how this works.
Steps to Follow >
➊ At first open the Ubuntu Terminal.
➋ Type the following command in the command prompt:
cd /➌ Now, press the ENTER button.
Output >
As you can see from the picture below that my initial location was in my Home directory from there I changed my location to the Root directory by using the cd command. You can actually see the contents of the Root directory using ls.
NB: pwd command tells your current working directory.

Example 3: Move Inside a Directory Using the “cd” Command in Linux
To move into a directory you have to use the cd command and the directory name. Now follow the steps below to see how this works. There is a directory named Sports in my home directory. I will access that directory. So follow the steps below.

Steps to Follow >
➊ At first open the Ubuntu Terminal.
➋ Type the following command in the command prompt:
cd Sports/Cricket/Bangladesh➌ Now, press the ENTER button.
Output >
As you can see initially I was in my Home directory. From there I gave the entire path of the Bangladesh directory. And that command changed my current directory location to the Bangladesh directory.
NB: pwd command tells your current working directory.
Example 5: Moving One Directory Backwards Using the “cd” Command
To move one location backward I will use the symbol “..” with the cd command. In the previous section, I changed my directory location to the Bangladesh directory. Now I will return to my Sports directory. Follow the steps below to see how this works.
Steps to Follow >
