How to install node red and recognizer

General
63

OK - a few examples of use/misuse of the node-red command (or script) - /usr/bin/node-red:
Maybe some or all of these only happen on my Linux computer?

  1. node-red admin rm
    The script prints the Usage message
Usage:
   node-red-admin <command> [args] [--help] [--userDir DIR] [--json]

Description:
   Node-RED command-line client

Commands:
   init    - Interactively generate a Node-RED settings file
   hash-pw - Creates a hash to use for Node-RED settings like "adminAuth"
   target  - Set or view the target URL and port like http://localhost:1880
   login   - Log user in to the target of the Node-RED admin API
   remove  - Remove the NPM module from Node-RED
etc

Excellent, I made a mistake and it told me about it.

  1. node-red stop or node-red version
    It happily assumes that I want to start Node-red using a flow file called stop or version. :crazy_face:

  2. node-red --version or node-red -version
    This seems to ignore the invalid parameter and starts Node-red using the default flows.json

  3. node-red please start
    Node-red starts up, expecting a flow file called please. Anything else at the end of the command is silently discarded!

It seems to me that this part of the core does not adequately parse it's arguments and print appropriate feedback.

A glance at the other thread I linked to above shows that people are falling foul of this issue.
