Cloud CLI Patterns

Credentials are pre-configured. Use --help or Context7 for syntax.

BigQuery

Copy# Always estimate cost first
bq query --dry_run --use_legacy_sql=false 'SELECT ...'

# Run query
bq query --use_legacy_sql=false --format=json 'SELECT ...'

# List tables
bq ls project:dataset

# Get table schema
bq show --schema --format=json project:dataset.table

Cost awareness: Charged per bytes scanned. Use --dry_run, partition tables, specify columns.

GCP (gcloud)

Copy# List resources
gcloud compute instances list --format=json

# Describe resource
gcloud compute instances describe INSTANCE --zone=ZONE --format=json

# Create with explicit project
gcloud compute instances create NAME --project=PROJECT --zone=ZONE

# Use --quiet for automation
gcloud compute instances delete NAME --quiet

AWS

Copy# List resources
aws ec2 describe-instances --output json

# With JMESPath filtering
aws ec2 describe-instances --query 'Reservations[].Instances[].InstanceId' --output text

# Explicit region
aws s3 ls s3://bucket --region us-west-2

# Dry run where available
aws ec2 run-instances --dry-run ...
