What is the command to change a file's ownership in Linux?

The command used to change a file's ownership in Linux is "chown." This command allows you to specify a new owner for a file or directory, which is essential for managing permissions and access control on a system. When using "chown," you can change the owner to a specific user or even a group if needed. The syntax typically involves "chown [new_owner] [file]" or "chown [new_owner]:[new_group] [file]" if you're modifying both user and group ownership.

Understanding the other commands can provide clarity on their specific purposes. "chmod" is used for changing the file permissions, controlling who can read, write, or execute a file. "chgrp" is utilized for changing the group ownership of a file, but it does not impact the user ownership. Finally, "mv" is a command for moving files or renaming them, which does not alter ownership. Thus, "chown" is the correct choice for changing a file's ownership.
