CHOWN(1) General Commands Manual CHOWN(1)
chown, chgrp - change owner or group
chown owner file ...
chgrp group file ...
Chown changes the owner of the files to owner. The owner may be either
a decimal UID or a login name found in the password file.
Chgrp changes the group-ID of the files to group. The group may be
either a decimal GID or a group name found in the group-ID file.
Only the super-user can change owner or group, in order to simplify as
yet unimplemented accounting procedures.
