What is the mv command used for in Linux?

The mv command in Linux is primarily used to move or rename files and directories. When you invoke this command, you can specify the source file or directory you want to move and the destination where you want it to be relocated. If the destination is an existing directory, the source file will be moved into that directory. On the other hand, if you provide a new file name as the destination, mv will rename the file or directory to that new name.

This command is essential for file management in a Linux environment as it helps maintain an organized file structure, allowing users to easily relocate files or rename them as needed. Understanding this command is crucial for anyone working within the Linux command line, as it forms the basis for effective file handling and organization. The other options relate to different functionalities in the Linux command line, such as viewing directory contents, creating directories, and copying files.
