Results are returned as a list of maps of String key/value pairs. The reason for this is that a command can return multiple results, which have multpile variables. For example, to print the names of all the interfaces returned in the command above, do:
|
||||||
|
|
||||||
|
```java
|
||||||
|
for (Map<String, String> map : rs) {
|
||||||
|
System.out.println(map.get("name"));
|

|
}
