How can you change the ownership of a file in Linux?

To change the ownership of a file in Linux, the appropriate command is 'chown.' This command explicitly allows you to change the user and/or group ownership of a file or directory. The syntax of the 'chown' command typically includes the new owner and the target file, allowing for precise modifications to ownership. For example, executing chown user:group filename will change both the owner and the group of the specified file to the given user and group.

The other commands serve different purposes: 'chmod' is used for changing the file permission settings, 'mv' is utilized for moving or renaming files, and 'chgrp' is specifically designed to change the group ownership of a file without changing the user ownership. Each of these commands plays a distinct role in file management within the Linux system, but when it comes to altering the ownership of a file, 'chown' is the correct choice.
