What does the 'mv' command do in Linux?

The 'mv' command in Linux is primarily used for moving files or directories from one location to another within the filesystem. When you specify a source file or directory and a destination, the command will relocate the specified item to the new location. It's important to note that this command can also be used to rename files or directories by providing a different name as the destination while keeping the source in the same directory. The functionality of 'mv' is fundamental for file management in Linux, making it essential to understand its capabilities for effective navigation and organization within the filesystem.
