0
I have situation below, but I want only that column two is only READY and nothing else.
kubectl get nodes | grep "<Ready>"
10.5.0.11-c76ed Ready,SchedulingDisabled
10.7.0.13-d5bba Ready
kubectl get nodes | grep -w Ready
10.5.0.11-c76ed Ready,SchedulingDisabled
10.7.0.13-d5bba Ready
I want this output:
10.7.0.13-d5bba Ready
awk grep kubernetes

Perhaps Ready could be at the end of the line:
kubectl get nodes | grep 'Ready$'
or almost at the end of the line, save for some whitespace:
kubectl get nodes | grep 'Ready[[:space:]]*$'
or perhaps the only thing in field 2:
kubectl get nodes | awk '$2 == "Ready"'

first one did not work.. second worked. ` kubectl get nodes | awk '$2 == "Ready"'`

I wasn't sure if the trailing space was from actual data or a formatting "typo". I've added a variation to the Answer to account for trailing spaces.
