OPERANDS
       The following operands shall be supported:
       owner[:group]
              A user ID and optional group ID to be assigned to file. The owner portion of this operand shall be a user  name  from  the  user  database  or  a
              numeric  user  ID.  Either  specifies  a  user ID which shall be given to each file named by one of the file operands. If a numeric owner operand
              exists in the user database as a user name, the user ID number associated with that user name shall be used as the user  ID.  Similarly,  if  the
              group  portion  of  this  operand is present, it shall be a group name from the group database or a numeric group ID. Either specifies a group ID
              which shall be given to each file. If a numeric group operand exists in the group database as a group name, the group ID number  associated  with
              that group name shall be used as the group ID.
       file   A pathname of a file whose user ID is to be modified.
