Hi folks.

I'm using a "Button node" to execute a Linux system command then I pass the payload to a "Exec node" then to a "Notification node". The problem is that the output is on one line like this:

 ![immagine](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/2/3/2397da36125aa9988dd4152c21d4d970c5b624a8.png).  
In "debug node" I see the output in the correct way

Is possible to have the output in the correct way also in "notification node"?

Thank you

Did you read the link , the first thing it shows is the pre tag around the text. so try putting it either side of the text, in the notification node.

```auto
<pre>the text you wish to keep formating of</pre>

```

The notification node allow html and css as far as i am aware.  
in a template node just before the notification node, `<pre>{{payload}}</pre>` were payload would be the property that holds the text.

Ok, but the text come from a command over Linux. My problem is to format that text...  
And the example you posted, show how to do it in pure HTML/CSS not in Nodered.

Can you tell me what can I do or not please? It seems it's a secret or a mystery...

No secret you just need to read the info provided. [The Core Nodes : Node-RED](https://nodered.org/docs/user-guide/nodes#template)

I've not read this part of your message. I'm on work and also not in my office. Sorry...

I've trying to put "Template node" with "\<pre\>{{payload}}\</pre\>" code inside, between "stdout exit of Exec node" and "input of Notification node", but the result is that there is **\<pre\>** on the beginning of output and **\</pre\>** to the end.

Try checking  
Accept raw HTML/JavaScript input in msg.payload to format popup  
In the template node.

Flagging **"_Accept raw HTML/JavaScript input_"** in Notification Node has resolved. Now output is leggible.  
Thank you very much for all

There is another little problem. I've noticed that the text between \<pre\> and \</pre\> is outputted in a "template node" as "normal text" and has no more CSS applied. Is possible to set CSS for a specific block?  
Thank you
