In programming, making assumptions is a path to unexpected failure.

You need to be able to handle gracefully the case where the command
given as a filter on either the local or the remote side will fail (for
whatever reason).  That is, your program will need to identify that it
failed, inform the user of the failure, and not cause any unexpected
action to occur as a result.
