Well, Cisco have a Master Index of all commands on IOS XR 
(CRS and ASR9000) in alphabetical order, for a handful of 
the recent software releases here:

http://www.cisco.com/en/US/products/ps5845/products_product_indices_list.html


You can definitely use that to gain an understanding of all 
the commands in IOS XR, how they're used and what they'll 
get you.

If it is your first time to IOS XR, I'd also recommend this 
very old but still useful link that compares common commands 
between IOS and IOS XR. It's not exhaustive, but it will get 
you started and pointed in the right direction:

http://www.cisco.com/en/US/docs/ios_xr_sw/iosxr_r3.5/xr12000_conversion/reference/guide/cn35main.html


We didn't go for any IOS XR training, but just by using 
these links, we've been able to deploy several CRS and 
ASR9000 systems in our network, as well as convert lots of 
IOS, IOS XE and Junos configurations to IOS XR, without any 
help from Cisco or their partners (much to their worry, 
initially, but then relief as we don't hassle them also), 
including managed router services for customers buying CRS 
routers that have no experience with IOS XR.

It's really not that hard, if you put your back into it.

Cheers,

Mark.
