Which command is used to change directories in Linux?

The command used to change directories in Linux is cd, which stands for "change directory." This command is fundamental to navigating the filesystem in a Linux environment. When you use cd followed by the name of a directory, the shell modifies the current working directory to the specified one. For example, typing cd Documents would take you into the Documents directory if it exists in the current directory.

This command plays a crucial role in command-line operation, enabling users to navigate through various directories to access files or execute other commands from different locations within the filesystem. Without the cd command, users wouldn't be able to switch between directories effectively.
