The command chown /ˈtʃoʊn/, an abbreviation of change owner, is used on Unix and Unix-like operating systems to change the owner of file system files, directories. Unprivileged (regular) users who wish to change the group membership of a file that they own may use chgrp.
The ownership of any file in the system may only be altered by a super-user. A user cannot give away ownership of a file, even when the user owns it. Similarly, only a member of a group can change a file's group ID to that group.[1]
The chown command has also been ported to the IBM i operating system.[2]
