I am using Screen via SSH to run a backup script on the host. The tricky thing is that I want a clean backup, so I'm stopping everything **including** Node-RED when doing it. I would like to be able to see on VNC if the script is still running, but that means that I need Screen to run the script in a window. I have tried to search around, but I haven't found an answer to that, probably because it's not a common use. The node is like this:
```auto
{
"id": "eb607f0925ac4680",
"type": "inject",
"z": "139a05b0e07293f9",
"name": "",
"props": [
{
"p": "payload"
},
{
"p": "topic",
"vt": "str"
}
],
"repeat": "",
"crontab": "",
"once": false,
"onceDelay": 0.1,
"topic": "",
"payload": "",
"payloadType": "date",
"x": 100,
"y": 400,
"wires": [
[
"fab1883caac56ce6"
]
]
},
{
"id": "fab1883caac56ce6",
"type": "exec",
"z": "139a05b0e07293f9",
"command": "sshpass -p \"SECRET_PASSWORD\" ssh pi@192.168.5.2 -o StrictHostKeyChecking=no \"screen -S sikkerhetskopiering -d -m /home/pi/sikkerhetskopiering.sh\"",
"addpay": "",
"append": "",
"useSpawn": "false",
"timer": "",
"winHide": false,
"oldrc": false,
"name": "Backup via Screen",
"x": 270,
"y": 400,
"wires": [
[
"e12ed03ace973a37"
],
[
"e12ed03ace973a37"
],
[
"e12ed03ace973a37"
]
]
},
{
"id": "e12ed03ace973a37",
"type": "debug",
"z": "139a05b0e07293f9",
"name": "debug 23",
"active": true,
"tosidebar": true,
"console": false,
"tostatus": false,
"complete": "false",
"statusVal": "",
"statusType": "auto",
"x": 460,
"y": 400,
"wires": []
}
]
```
So the SSH command is:
```auto
sshpass -p "SECRET_PASSWORD" ssh pi@192.168.5.2 -o StrictHostKeyChecking=no "screen -S sikkerhetskopiering -d -m /home/pi/sikkerhetskopiering.sh"
```
Is there a way to do what I want, or is that just not possible?

If you are running screen on the remote device, you should be able to reconnect to the screen session from a different terminal. Have a look at the screen commands. Been a long time since I used it so I don't know the commands off the top of my head.

I don't know if Docker makes a difference, but regarding running commands over ssh on another device:
Can't you tell that the script is still running because the exec node has not sent a message on it's return code output?
And if you set the exec node to send output while the command is running, you can see progress messages from your script.

@TotallyInformation I have tried to find some way to do it, but it maybe over my head...
@jbudd Well, as I said, I am stopping everything with the script **including** Node-RED, so there is no node to receive the message.

Oh, finally found it! I can use `screen -ls`, which will show me the running sessions as numbers, let's say it's 92358 and then `screen -r 92358` to connect to it!

But you are running the command from node red on a "separate" machine?
Oh you solved it. 😀

Yep, I did! 👍 But no, I'm running the command on the only Pi that I have in my car, so a Docker instance running on the host that runs the script. No other Pi's are connected to that network to send the command, and I'm automating a backup to a directory named after date and time every night at 04.30. The window is a safeguard if it stops on something I will be able to connect to it with VNC and see what's holding it up.
