The command changes the owner and, optionally, group for one or more
files and directories. The value for file can be a full or partial
path. The value for owner can be either a decimal UID or a login name
found in the password file. The value for group can be either a deci‐
mal GID or a group name found in the group file.

can also change the group of a file. The owner of a file can only
change the group, but the owner must be a member of any group speci‐
Options-f Inhibits display of errors that are returned when cannot change
the owner or group of the specified files.
-R Causes to recursively descend any directories subordinate to file
