How to change the shell working directory in Linux?

To change the shell working directory, we use the cd command in the Linux system. The cd (change directory) command is one of the most fundamental navigation commands that allows users to move between different directories in the filesystem.

cd (change directory)

The cd command is used to change the current working directory in Linux/Unix operating systems. It is equivalent to the cd or chdir command in Windows. The command is also available in the EFI shell (Extensible Firmware Shell). By default, when you open a new terminal session, the current working directory is set to your home directory.

Syntax

The general syntax of the cd command is as follows −

cd [-L| [-P [-e]] [-@]] [directory]

Options

The following table describes the options available with the cd command −

Common Usage Examples

Basic Directory Navigation

To change from the current directory to a specific directory, use −

$ cd Documents

This changes the working directory to the "Documents" folder in the current location.

Navigate to Home Directory

To change the current working directory to your home directory, use the tilde (~) symbol −

$ cd ~

Alternatively, you can use cd without any arguments −

$ cd

Navigate to Parent Directory

To move up one level to the parent directory, use two dots −

$ cd ..

Navigate Using Absolute Paths

To navigate to a directory using its absolute path −

$ cd /usr/local/bin

Navigate Using Relative Paths

To navigate to a subdirectory within the current directory −

$ cd shadow/snow

This navigates to the "snow" directory inside the "shadow" directory.

Checking Current Directory

To verify your current working directory, use the pwd (print working directory) command −

$ pwd

If you are in your home directory, the output will be similar to −

/home/username

Getting Help

$ cd --help

Key Points

• The cd command without arguments takes you to your home directory

• Use cd .. to move to the parent directory

• Both absolute paths (starting with /) and relative paths are supported

• The pwd command helps verify your current location

• Tab completion can help you navigate directories more efficiently

Conclusion

The cd command is essential for navigating the Linux filesystem. Understanding its basic usage patterns?moving to specific directories, returning home, and navigating parent directories?forms the foundation of effective command-line navigation in Linux systems.
