Guide to VMware ESX Server 3

I found a link with a very nice and useful guide with commands to administer VMware ESX 3, there are commands like:

esxcfg-info
Produces an enormous amount of information about the ESX host. You really need to pipe this to a file for closer examination!

[root@esx1host root]# esxcfg-info >esxinfo.txt

and much more!!!

and if you are still running VMware ESX 2.x, there is a guide for that version too!
