What is the function of the 'mv' command?

The 'mv' command in Linux is primarily used to move files or directories from one location to another. This command allows users to specify the source file or directory and the destination where they want to move it. When the 'mv' command is executed, the file is removed from the original location and placed in the new one, effectively changing its position in the file system.

Additionally, if the destination specified is in the same directory as the source but with a different filename, the 'mv' command can also be used to rename files. This versatility makes 'mv' an essential tool for file management in a Linux environment. The command can also overwrite existing files at the destination, depending on the options used with it, giving users control over file handling during the move process.

This command does not function to list files, copy files, or create directories, which are roles served by the 'ls', 'cp', and 'mkdir' commands, respectively.
