For the moment, there is no other value to associate with, so we would do something like NS_MAP["$ns"]=1. We could link the name of the global variable, but that's not needed for the tests for the moment. Also, I don't know if it is important, but when we will iterate over the list of netns, it will not be done following the same order items have been added into the hashmap. So we will change the order in which items are deleted. > OTOH, perhaps this breaks with older versions of bash that we still > care about. Good point. I don't have the answer, but associative arrays are starting to be quite old now :) Cheers, Matt -- Sponsored by the NGI0 Core fund.
