I've used "ip" a couple times. I mostly use ifconfig, because it's  
there and I see no upside in using "ip". I also use iwlist and  
ifenslave and tunctl and various other tools. Does ip have some kind of  
plugin architecture to suck all that into one big monolithic command?

In what way? I vaguely recall first hearing about "ip" back under Red  
Hat 9, which shipped in 2003. So I've been successfully largely  
ignoring it for 10 years now. What's queued up to change in the near  
future?

Is there a standard on this? I'm happy to implement a standard...

Can use the ip command to manipulate the arp cache too? [checks] Of  
course you can. So for me to implement "ip" is as much code as for me  
to implement _how_ many other commands? Does it have code for moving  
interfaces into and out of containers too?

$ man ip | wc -l
1853
$ man ifconfig | wc -l
185

Oh yes, obviously a much simpler command than ifconfig. Obvious choice,  
really. (How do I trigger the built in dhcp client, I'm not finding it  
in the man page. Did ubuntu not compile that in? I vaguely remember  
using it once...)

$ man bash | wc -l
5459

I suppose I can take solace that the bash man page is almost 3 times as  
long as the ip man page...
