How do you change directories in Linux?

To change directories in Linux, the 'cd' command is utilized. This command allows users to navigate between different directories within the filesystem. When you enter 'cd' followed by the desired directory name, the shell updates the current working directory to the specified one.

For example, using 'cd /home/user/Documents' would switch the current directory to the Documents folder located in the user’s home directory. Additionally, using 'cd ..' will take you up one level to the parent directory, making 'cd' a versatile command for managing your location within the file structure.

The other options provided do not perform the task of changing directories. The 'mv' command is used for moving or renaming files and directories, while 'change dir' and 'directory' are not valid commands in Linux. Understanding the use of 'cd' is fundamental for effective navigation and file management in the Linux environment.
