What does the 'cd' command do?

The 'cd' command stands for "change directory." It is a fundamental command used in command-line interfaces to navigate between different folders or directories within a filesystem. When you use the 'cd' command followed by the name of a directory, it tells the operating system to switch the current working directory to the specified one. This is essential for organizing files and managing different working areas in the filesystem.

For example, if you are in a directory called 'Documents' and you want to move to a subdirectory called 'Reports', you would type 'cd Reports'. Once this command is executed, your current directory changes to 'Reports', allowing you to interact with the files and subdirectories contained within it. This command is a basic yet crucial part of file and directory management in various operating systems, including Unix, Linux, and Windows, making it important for users to become familiar with it.
