Hope you don't mind my comment (I'm a fan of awk):
You can write

VMS=`vim-cmd vmsvc/getallvms | grep -v Vmid | awk '{print $1}'`

as

VMS=$(vim-cmd vmsvc/getallvms | awk '!/Vmid/{print $1}')

which saves a subprocess (grep)

Hi! Thanks for your script!
If you have comments in yor VM's, the script will output some errors like:

(vim.fault.NotFound) {
faultCause = (vmodl.MethodFault) null,
faultMessage =
msg = "Unable to find a VM corresponding to "something in the comment"
}

To keep this nice and beautiful, I added a regex check for numeric values in the for-loop:

#!/bin/sh
VMS=vim-cmd vmsvc/getallvms | grep -v Vmid | awk '{print $1}'
for VM in $VMS ; do
if echo $VM | grep -e '^[0-9]' >/dev/null; then
# echo "Probing VM with id: $VM."
PWR=vim-cmd vmsvc/power.getstate $VM | grep -v "Retrieved runtime info"
name=vim-cmd vmsvc/get.config $VM | grep -i "name =" | awk '{print $3}' | head -1 | awk -F'"' '{print $2}'
echo "VM with id $VM has power state $PWR (name = $name)."
fi
done

Hi, can you update for just show the power on VMs, not all. Many Thanks.
