I can do better ;)
If you are really doing this kind of things, you could use :
rmmod veth
Note that "ip" command supports a batch mode
ip -batch filename
In this case, the caching is done only once.
Eric, Stephen, one possibility would be to use the cache only in batch
mode.
Anyway caching is wrong because several users can use ip command at the
same time.
