If I want to use msg.payload in the command line of the EXEC node, is this possible? I tried using {msg.payload} as well as two and three mustaches without success. Anyone know how to do this?

No, but you can use a template node to build the payload you want before the exec node and then use the `append payload` option (iirc you can leave the command empty in the config so the whole cmd line can be passed in as the msg.payload)

Appreciate the suggestion but I failed to mention in my original post, I need to insert a variable in the middle of the command string. The reason for my question was I was hoping to avoid having to insert another node in front of the EXEC node. If that's not possible, I'll just use a Function node and move on.

You can't use moustache but you can insert a value into the command - just tick the append msg.payload to append it then any other parameters afterwards...

You should be able to assemble a command line with Jsonata in an inject node, something like this (`ifconfig wlan0 | grep inet`)

@jbudd... thanks I think will work for my situation.
