Which command is used to change directories in a Linux system?

In a Linux system, the command used to change directories is "cd." This command stands for "change directory" and allows the user to navigate to different folders within the file system. When you enter "cd" followed by the name of a directory, the system changes the current working directory to the specified one. This is fundamental for file management and navigation in the Linux command line environment, enabling users to move between directories easily.

The other commands serve different purposes: "ls" is used to list the contents of the current directory; "mv" is utilized for moving or renaming files and directories; and "pwd" (print working directory) displays the current directory you are located in. Understanding the specific functions of these commands helps users perform tasks efficiently in the Linux operating system.
