I am running below command in openshift platform which produces some output

oc get pods

name status

job1 Running

job2 Completed

How to extract only status from the above result and store it in a variable using shell script.

ex : status=completed

If you add --output=json to your commands you can use JQ to select the status. I find bash scripts great for using commands but there are a lot of drawbacks when it comes to parsing output. With JSON you can regardless of the format select the correct key.

Try status=$(oc get pods -o=custom-columns=STATUS:.status.phase --no-headers). You can echo $status and see the list of status saved in the environment variable.
