Google Cloud CLI (gcloud): Output and filtering

Choose the output format

Print results as JSON. Other formats include yaml, table and value.

gcloud compute instances list --format json

Capture a single value

Print a bare field, suited to scripts.

PROJECT=$(gcloud config get-value project)

Filter resources

Filter results on the server side.

gcloud compute instances list --filter "status=RUNNING AND zone:us-central1"

Skip confirmation prompts

Accept defaults without asking, as scripts need.

gcloud compute instances delete my-vm --zone us-central1-a --quiet

Caution: --quiet confirms destructive actions for you.
