I use:

@Frida Although that may work, It also will attempt to start a Node-Red instance on the default port.

Yes I know. But when it runs in advance, nothing happens, otherwise you can stop it again.

The file location would have to be changed depending on your system setup of course.

There is no such command line parameter as `--version`. You are needlessly starting a NR instance.
Use `-?` as mentioned earlier.

The --version was a suggestion, but -? trumps that idea to be sure.

node-red -? doesn't seem to work for me. Appears to be due to zsh.
```auto
> node-red -?
zsh: no matches found: -?
> node-red --help
Node-RED v2.2.2
Usage: node-red [-v] [-?] [--settings settings.js] [--userDir DIR]

Options:
-p, --port PORT port to listen on
-s, --settings FILE use specified settings file
--title TITLE process window title
-u, --userDir DIR use specified user directory
-v, --verbose enable verbose output
--safe enable safe mode
-D, --define X=Y overwrite value in settings file

I'm aware, hence the second command in the screenshot, thank you though. `node-red -?` works fine when I switch to bash. Just thought I'd mention it, in case any future readers have this issue.

### Windows...
`node-red --help | findStr Node-RED`

`node-red --help | grep Node-RED`
### ANY OS (using `node`)
`node -p "require('path/to/node-red/package.json').version"`

Tangent question... how to find the installation date? Thinking just stat the nod-red executable?
# stat /usr/bin/node-red
File: /usr/bin/node-red -\> ../lib/node\_modules/node-red/red.js

Birth: 2022-02-19 21:40:12.665240108 +0000
So the birth time stamp?
The installation script I use tracks the invocation stamp, so that is a reference but always nice to have a validation check, such as catch if someone else reinstalled an application at a later date from the official stamp.
