NAME
chown - change owner

SYNOPSIS
chown [ -Rf ] owner[.group] file ...

DESCRIPTION
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.
An optional group may also be specified. 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, in order to simplify
accounting procedures. No errors, except for usage errors, are
reported when the -f (force) option is given.

When the -R option is given, chown recursively descends its
directory arguments setting the specified owner. When symbolic
links are encountered, their ownership is changed, but they are not
traversed.
