Do you do that continuously to detect when the link goes down? That
sounds like a lot of overhead.

Good point. I may have misunderstood the scenario. I thought the OP
was looking to detect that in a script, not in a real time situation.
For that I do not know how it could be done with low overhead. The
best I can suggest would be a crontab executing every x minutes
depending on the requirements of the OP.
