If you want to change your current directory in Linux, which command will you use?

The command used to change the current directory in Linux is "cd." This command stands for "change directory" and is essential for navigation within the file system. When you type "cd" followed by the name of a directory, the shell updates your current working directory to the specified directory, enabling you to perform operations within that directory.

For example, if you want to navigate to a directory called "Documents," you would enter the command cd Documents. After executing this command, the shell context changes and you'll be working within the "Documents" directory.

The other commands have different purposes: "cat" is used to concatenate and display the contents of files, "ls" lists the contents of a directory, and "echo" outputs a string or variable to the terminal. None of these commands are designed to change the current directory, which is why "cd" is the appropriate choice for this task.
