I have attempted to craft a flow that sets a `flow variable` in `file` context storage to a string with the value being the `IP:PORT` of Node-RED and display in status of function.
The only non core node used is `node-red-contrib-string` (I will see about removing this in the future, but for testing/developing it saves me time).
If you have a minute to test it for me, it would be greatly appreciated. If you choose to, could you respond with whether or not the resulting status was valid for your install (if `http://IP:PORT/` or `https://IP:PORT/` brings up the editor, report valid). And if any modifications were used to get it to function correctly, or any recommendations.
My goal is to make it function correctly on as many Node-RED installation configurations as possible.

It does not.
Note that on, for example Debian, there is no netstat available out of the box. Some other commands like lsof require sudo/root to get the details of processes. And the output could differ across operating systems.
What is consistent between OS'es is the settings.js path & file. You use a file read node, path: `./.node-red/settings.js` and grep the port from it with a change node using a regular expression/jsonata. eg: `$match(payload, /PORT \|\|.([0-9]+)/).groups[0].$number()`
Only thing left is the ip address. On linux you can get this via `hostname -I`

@bakman2 I like your approach, but the `read file` node's path isn't universal either as it doesn't work on my WSL instance of Node-RED.

hmm where is it located then ?
in that case you may want to add an additional flow to check what OS/filesystem it is first.
i though the read file node would handle double slashes, but apperently it does not

That is only if you use backslashes. Forward slashes should work fine on Windows.

Is does not, because `pwd` gets the path of the working directory, which is above the `.node-red` dir, will need to add `/.node-red`

Running flow3 on macOS Montery (v12.5) I get `undefined:1880`
EDIT: Running the `get ip` exec commands in a cli I get:
```auto
Paul@PaulsM1 ~ % hostname -I | cut -d ' ' -f1 | tr -d '\n'
hostname: illegal option -- I
usage: hostname [-f] [-s | -d] [name-of-host]
Paul@PaulsM1 ~ % hostname
PaulsM1.local
Paul@PaulsM1 ~ %
```

Yes cross platform remains a challenge, requires multiple if/else checks.

@zenofmud Would `PaulsM1.local:1880` be valid for your editor?

It is not a good idea to assume anything about the current directory in node-red. It may also depend on how node-red is installed and run.

Yes, that does bring up the editor.

If `flow 4` does not work for you please confirm your:
OS
Node-RED install location
Description of any errors

same as this:

> Is does not, because pwd gets the path of the working directory, which is above the .node-red dir, will need to add /.node-red

It does not. In macOS the name is 'Darwin'
Changing the IF to test for a 'd' and it works
