Given the output listed on describe-listeners — AWS CLI Command Reference, the command would be:

aws elbv2 describe-listeners --query 'Listeners[].ListenerArn'

If you want the output as just text, with one entry per line, use:

aws elbv2 describe-listeners --query 'Listeners[].[ListenerArn]' --output text

The --query parameter uses JMESPath. I highly recommend the JMESPath Tutorial.

  • I suggest that you **ask a new Question** because this is raising other issues that are unrelated to this Question. When you create a new Question, please explain your _actual_ goal (that is, what you'd like to achieve) because there might be a different way to achieve that objective. – John Rotenstein Nov 16 '22 at 21:23
