Complete the following:\n\n1. List all pods in the `default` namespace **sorted by their creation timestamp** (oldest first) and save the output to `/tmp/pods-sorted.txt`\n2. List all pods sorted by name and save to `/tmp/pods-by-name.txt`\n\n```bash\n# Sort by creation time:\nkubectl get pods --sort-by=.metadata.creationTimestamp\n\n# Sort by name:\nkubectl get pods --sort-by=.metadata.name\n```",
