# Multiple Command-Node

This is an example showcasing how admins can remotely execute **_multiple commands_** via the "zero trust host access" control channel on specific nodes in Rafay MKS clusters operating in remote data centers.

* * *

## Request API

In this example, we want to send two distinct and separate commands to the specified nodes.

1. free -h
2. lsblk

As you can see, the two commands are sent together separated by a ";" in the highlighted line below.

```
curl --location --request POST 'https://console.rafay.dev/cmdexec/v1/projects/j2q4j5k/edges/3mxg7ek/execute/' \
--header 'X-RAFAY-API-KEYID: g5439debbd24b1c876aa79b4d2997bdca7009f3g' \
--header 'Content-Type: application/json' \
--data-raw '{\n    "target" : ["madhuarm-ubuntu201","madhuamd-ubuntu201"],\n    "target_type" : "node",\n    "command": "free -h ;lsblk",\n    "content_type": "string",\n    "timeout": 360\n}'
```

The output returns data and an "Exec ID" which can then be used to query for results of the responses.

* * *

### Retrieve Results

We will use the Exec ID to retrieve results.

```
curl --location --request GET 'https://console.rafay.dev/cmdexec/v1/projects/j2q4j5k/edges/3mxg7ek/execution/q6kn4ml/' \
--header 'X-RAFAY-API-KEYID: fg5439debbd24b1c876aa79b4d2997bdca7009f3g'
```

Shown below is an example of what the results can look like.
