The cd command is a crucial tool for accessing the file system by altering the current working directory when using the Linux command line interface. You can navigate between directories and access files and directories on your Linux system by learning how to use the cd command. We’ll go through how to use the cd command correctly in this post and examine all of its features.

How to Use the Linux cd Command
Change Directory is the meaning of the cd command using terminal. Cd, one of Linux’s most basic commands, is now used everywhere to change folders. There are also several other command implementations available, like chdir for MS-DOS platforms.
Fundamental Syntax
The basic syntax for the cd command is:
cd [options] [path]In the command above:
- Uses the cd command when entered.
- [options]: Including options modifies how the command operates.
- [directory]: The directory’s path where you want to move to.
In its most basic form, cd will transport you to your home directory when invoked without any arguments.
You can use the Tab key to have the names of directories autocomplete while traversing the file system. It is not required to conclude the directory name with a slash. You need to have executable permissions on a directory in order to switch to it.
To display the full path of your current directory, enter the following command:
pwdAbsolute and Relative Path Names
Both absolute and relative path names can be used to identify a directory to change to. The full or absolute path begins at the system root /, while the relative path begins in the current directory.
Your home directory is the default setting for your current working directory when you log into a Linux system. If the Downloads directory is present in your home directory, you can access it by using the relative directory path:
cd DownloadsUsing its absolute path, you can access the same directory as well:
cd /home/username/DownloadsSimply put, the absolute path to the directory is one that begins with a slash (/).To easily go to different directories without having to write the entire pathname, Cd keeps track of which directories are above and below the current directory.
Use the ls command to list down every directory in that folder if you are confused of the exact name of the subdirectory you wish to go to.
Go to the Parent Directory
A directory that has one or more subdirectories is referred to as the parent directory. In other words, if you’re /home directory contains the directories /Desktop and /Downloads, then that directory will serve as the parent directory for those two folders.
The letters .. and. stand for the parent directory and the current directory, respectively.
Switch to the parent directory by using the double-dot character (..).
cd ..You can go up the directory tree one level with the aforementioned command. You can advance up the directory tree by passing more. characters.
Moving two levels up from your current working directory:
cd ../../A specific directory can also be supplied that is one level above the the working directory at present.
cd ../../To Change the Previous Working Directory
The – (hyphen) character makes it simple to return to the previous working directory while working with many directories at once.
If your current working directory is /home and you change to /root, as an illustration. Then the working directory will change to /root, and the working directory before that was /home.
You can return to the previous directory, /home, by typing the following command.
cd -Additionally, using the cd command and then a space will return the user to their previous working directory.
cd Switch to the Home Directory
The /home directory is a particular location on a Linux system designated for a user’s private documents, applications, and subfolders. The home directory is automatically configured as the current working directory when you log in to your system.
The ~ (tilde) character has been designated as a special character for the home directory.With the cd command, you can simply pass the ~ character to change the current working directory to /home rather than entering the full path to your home directory (/home/username).
cd ~You can follow these steps to navigate to another user’s home directory.
cd ~usernameWe changed the current working directory to /Desktop in the previous section. You can reduce the size of the command to half by using the character to indicate the /home directory.
cd ~/DesktopNavigate to the Root Folder
The / character in a Linux-based operating system stands for the /root directory, just like the home directory. The root folder can be reached at any time by:
cd /Make the switch to a directory name with spaces
Your computer’s folder names won’t all be single words. The character “space” may be present in some of them. as in /home/username/Important Documents.
The directory name will not be specified in such cases, and an error will be returned.
cd /Important Documentsoutput
bash: cd: too many argumentsUse quotes around the pathname to change to directories that have spaces in their names. Please take note that the command supports both single and double quotes.
cd 'Important Documents'
cd "Important Documents"
As an alternative, you can remove spaces by using the backslash () character.
cd Important\ DocumentsChanging Directory and List Content
To switch to a new directory and list its contents at the same time, add the ls command to the cd command using the && flag.
cd [path to directory] && lsUsing the above example:
cd Example_Directory && lsAutocomplete Directory Name
The Linux terminal doesn’t have autocomplete by default. You can install and configure bash-completion package and use the autocomplete feature. If you don’t know the name of the directory you’re trying to move to you can press press the Tab key on your computer following the command.
cd X[Tab]Conclusion
After reading this guide, you ought to be able to use the Linux cd command to navigate around and alter the current working directory in the terminal window. Please feel free to share your thoughts and feedback in the comment section below.
“The Linux terminal has an autocomplete feature”
No it does not.
The autcomplete feature is a feature of whichever shell which you are using (most probably but not necessarily bash). cd is a built in command of the Bourne Again Shell (bash), as well as other shells (tcsh, zsh etc).
And is there no love for the change directory related commands pushd and popd?
