+# Output CLI Results In Different Formats
+
+The AWS CLI can output the results of commands in three different formats.
+
+- Text
+- JSON
+- Table
+
+The _default_ output format for my AWS CLI is currently configured to `json`.
+
+```bash
+$ aws configure get output
+json
+```
+
+I can either accept the default or I can override it with the `--output` flag.
+
+```bash
+$ aws rds describe-db-instances \
+  --query 'DBInstances[*].Endpoint' \
+  --no-cli-pager
+[
+    {
+        "Address": "fc-database-abcefg-ab1c23de.asdfgh4zxcvb.us-east-2.rds.amazonaws.com",
+        "Port": 5432,
+        "HostedZoneId": "A1BCDE2FG345H6"
+    }
+]
+
+$ aws rds describe-db-instances \
+  --query 'DBInstances[*].Endpoint' \
+  --no-cli-pager \
+  --output table
