+# targets
+
+[← Command Reference](../commands.md)
+
+List all registered targets. The active target is marked with `*`.
+
+## Usage
+
+```
+uaa targets
+```
+
+## Global Flags
+
+| Flag | Short | Description |
+|------|-------|-------------|
+| `--verbose` | `-v` | Print additional info on HTTP requests |
+
+## Output
+
+Each target is printed on its own line with a 1-based index. The currently active target is prefixed with `*`:
+
+```
+* 1: https://uaa.example.com
+  2: http://localhost:8080/uaa
+```
+
+If no targets have been registered, the command prints `No targets set.` and exits 0.
+
+## Examples
+
+```bash
+# Register two targets and list them
+uaa target https://uaa.example.com
+uaa target http://localhost:8080/uaa --skip-ssl-validation
+uaa targets
+```
