 	echo "$MESSAGE" 1>&2

assigned to that sub-shell, rather than (as here in your 
approach) trying to write directly to a device to which it 
does not have rights

I am not against error logging, but the unusual way it is 
attempted, in view of the Unix and CentOS rights model as to 
selected devices
