SnapshotCreateTimeが最大のスナップショットのSnapshotIdentifierを取得し、それをClusterIdentifierでフィルタリングしたいとします。ここでjson docのチェーン選択とmax_byとbashのjq
aws redshift describe-cluster-snapshots --region us-west-2 |
jq -r '.Snapshots[]
| select(.ClusterIdentifier == "dev-cluster")
| max_by(.SnapshotCreateTime)
| .SnapshotIdentifier '
JSON
