8-) ofcourse i overdraw and provoked.

if it _would_ be simple, minimal and useful then nobody would use 'ip'

cat makes sense, ls is useful enough that we all can live with it's
errors. (i dont know a better tool to do this job).

- all the IPv6 stuff
- CIDR-notation
- aliases + multiple IP's on one interface
- correct output of aliases
- tunnels
- more than one routing table ("policy routing")
- preparing traffic control
- better readable scripts (!)
  e.g. get the default route: 'ip route list exact 0/0'
- better parseable output (if needed, e.g. ip -oneline link show tun0)
- you can rename interfaces
- multicast working
- fine control over all netlink-params (e.g. txqueuelen)

- http://www.reddit.com/r/networking/comments/1a7z6z/the_missing_man_page_for_ifconfig_xpost_from/

ofcourse i'am fine with both implementations, but IMHO
it's better to let 'ifconfig' die, than to enforce people
to learn the syntax for 4 tools (ifconfig, route, arp,
netstat - which are doing the same (manipulating network-stack) but
inconsitently), instead of 1 tool which has the same clean
syntax everywhere.
