kubectl get namespaces

# Output format
kubectl get pods -o wide  # Detailed output
kubectl get pods -o yaml  # YAML format
kubectl get pods -o json  # JSON format
kubectl get pods -o name  # Names only
kubectl get pods -o custom-columns=NAME:.metadata.name,STATUS:.status.phase

# Filtering
kubectl get pods -l app=myapp  # By label
kubectl get pods -l "app in (frontend, backend)"
kubectl get pods --field-selector status.phase=Running
kubectl get pods -n production

# All namespaces
kubectl get pods -A
kubectl get pods --all-namespaces

# Watch
kubectl get pods -w
kubectl get pods --watch

# Watch with filtering
kubectl get pods -l app=myapp -w
kubectl get pods -n production -w
kubectl get pods --field-selector status.phase=Running -w

# Sorting
kubectl get pods --sort-by=.metadata.creationTimestamp
kubectl get pods --sort-by=.status.startTime
kubectl get pods --sort-by=.status.containerStatuses[0].restartCount

# All resource types
kubectl api-resources
kubectl api-versions

# Help

kubectl get pods --help
```

**Tips:**
- Use `-o wide` for detailed information.
- Use `-o yaml` for debugging.
- Use `-w` for real-time monitoring.
