CLI in VMWare

1. Can we use vCLI/PowerCLI/Shell on vCenter Server OR connect to VCS? If so, how?
2. What is the difference between  vCLI, PowerCLI and PowerShell commands ie.when do we use them.
3. What is EXTOP and RESXTOP? When do we use it specifically?
4. Are there any other simplified CLI tools to be used with vmware.
Thanks.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years.

AFAIK PowerCLI is the only CLI way to access VMware from remote. Other stuff is available only on the VMware host CLI itself.
You can't access VMware in PowerShell without PowerCLI. And PowerCLI only works in PowerShell.
I can't answer the parts about vCLI, EXTOP and RESXTOP.

1. Depends on your usage of OR. Is it logixal XOR or AND?
2. what is the difference between a car, a wheel and the road?
3. you dont. if you have vcenter you never see them.
4. PERL API?

I would recommend using the following, also VMware recommends the use of PowerCLI, which is PowerShell interface with vSphere-specific additions.

http://communities.vmware.com/community/vmtn/server/vsphere/automationtools/powercli

One of the simplest PowerCLI examples, and something which is actually extremely useful on its own, is the Get-VM cmdlet. Which lists VMs.

PowerCLI can be a bit overwhelming to use,  But it can be enhanced with a nice toolset and a library of preconfigured scripts to jump-start your mass changes, which is possible with PowerGUI

and

VMware Community Pack

It's also worth looking at The free VMware Guest Console

http://labs.vmware.com/flings/vgc

The free VMware Guest Console, an experimental application created by VMware Labs, is a great tool for managing vSphere VM processes and files. You can view, sort and kill processes across all VMs, and you can also run a script on all Windows or Linux VMs.

If you do want a script, LucD (1 of *the* premier PowerCLI gurus; literally co-wrote the book on PowerCLI :) ) provides a script in the following link:
