How to parse ISO8601 dates with linux date command
I’m trying to use the date command to generate a file timestamp that the date command itself can interpret. However, the date command does not seem to like its own output, and I am not sure how to work around this. Case in point:

The difference between ip link down and physical link absence
In Linux, is there any difference between after-ip link down-condition and real link absence (e.g. the switch’s port burned down, or someone tripped over a wire).
By difference I mean some signs in the system that can be used to distinguish these two conditions.
E.g. will routing table be identical in these two cases? Will ethtool or something else show the same things? Is there some tool/utility which can distinguish these conditions?
