hello
I would apreciate the support how to run this sett of linux/raspbian commands. ( using exec node?) if so how?
```auto
# Stop Zigbee2MQTT and go to directory
sudo systemctl stop zigbee2mqtt
cd /opt/zigbee2mqtt
# Backup configuration
cp -R data data-backup
# Update
git checkout HEAD -- npm-shrinkwrap.json
git fetch
git checkout dev # Change 'dev' to 'master' to switch back to the release version
git pull
npm ci
# Restore configuration
cp -R data-backup/* data
rm -rf data-backup
# Start Zigbee2MQTT
sudo systemctl start zigbee2mqtt
```

1. Add the commands to a shell script
2. Call the shell script from the exec node

In addition you will have to allow the user that is running node red to perform those sudo commands without having to provide a password (as you cannot provide a password via the exec node). You can do that using `sudo visudo`.
