Ideal command to get the sorted list is kubectl top node --no-headers --sort-by='cpu' | head -1 > somefilename.txt, but the result will be inconsistent due to open issue kubectl top issue

As a workaround you can try this command if you are running in any linux/mac OS:

kubectl top node --no-headers | sort -k3 -n | tail -1 > somefilename.txt

This issue has been resolved in kubectl 1.18.
