How to get installed version of NR?

zenofmud · 20 February 2022 00:35

If you enter node-red -? you get the help back and the version number is in the first line:

pi@fastpi:~ $ node-red -?
Node-RED v2.1.4
Usage: node-red [-v] [-?] [--settings settings.js] [--userDir DIR]
                [--port PORT] [--title TITLE] [--safe] [flows.json]
       node-red admin <command> [args] [-?] [--userDir DIR] [--json]

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
  -?, --help           show this help

@zenofmud , LOL! How did I miss that one!

Frida · 20 February 2022 14:14

I use:

pi @ raspberrypi: ~ $ node-red --version
20 Feb 15:10:02 - [info]

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

Frida · 20 February 2022 15:20

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

HaroldPetersInskipp · 20 February 2022 15:38

The method I've been using pulls it from .node-red/.config.nodes.json

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.

Nodi.Rubrum · 20 February 2022 21:39

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

HaroldPetersInskipp · 20 February 2022 22:50

node-red -? doesn't seem to work for me. Appears to be due to zsh.

try this node-red --help | grep Node-RED

HaroldPetersInskipp · 21 February 2022 17:10

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.

Steve-Mcl · 21 February 2022 18:12

And for completeness

Windows...

node-red --help | findStr Node-RED

Linux...

node-red --help | grep Node-RED

ANY OS (using `node`)

node -p "require('path/to/node-red/package.json').version"

e.g. ubuntu

e.g. windows

Nodi.Rubrum · 21 February 2022 22:43

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
Size: 35 Blocks: 0 IO Block: 4096 symbolic link
Device: b302h/45826d Inode: 17309 Links: 1
Access: (0777/lrwxrwxrwx) Uid: ( 0/ root) Gid: ( 0/ root)
Access: 2022-02-19 21:40:12.665240108 +0000
Modify: 2022-02-19 21:40:12.665240108 +0000
Change: 2022-02-19 21:40:12.665240108 +0000
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.
