Thanks Mike.
I use Ubuntu on the laptop and in the manpage for the ip command it has
the following:
COMMAND
...*As a rule, it is possible to add,**
** delete and **show (or list )**objects, but some objects do not
allow all**
** of these operations or have some additional commands.* ...
Seems to be vaguely documented - I can see how *(or list )* part can be
misleading as you might think they are just saying that show
_will_list_ and not necessary that *list* can be substituted for *show*
- it's all in the wording!
Oddly, the man page for ip (iproute-2.6.18-13.el5) on CentOS 5 is way
more comprehensive (it has way more examples on where list can be used)
than that on Ubuntu 14.04.1 with iproute-3.12.0-2! But then, Ubuntu has
a man page for each ip object:
$ man ip-<tab>
ip-address ip-monitor ip-ntable ip-tunnel
ip-addrlabel ip-mroute ip-route ip-xfrm
ip-l2tp ip-neighbour ip-rule
ip-link ip-netconf ip-tcp_metrics
ip-maddress ip-netns ip-token
