Hi,  
I dev. some node to recreate my settings.js file on a **new machine**  
**Warning :** If you have specifics settings.js or low NR experience don't try this node

I use sublflow $env variable to modify this scripting (i turn off recreate the file for the NR Padawan)

[flows\_.json](https://discourse.nodered.org/uploads/short-url/oMC734157lHnMzSgDI2rHf0U9rK.json) (51.6 KB)

Everythings is working fine except the password generator using the command (payload is the pass to /hash) :

**node -e "console.log(require('bcryptjs').hashSync(process.argv[1], 8));" {{payload}}**

I try also using the command : \*\*node-red admin hash-pw" --\> it's working but ask user entry and i don't know how to manage user entry (in scripting bash)

If you have some optimisations,comments... tell me.

Thanks

Regards

If you are writing a custom node, why not use the bcryptjs module directly?

But honestly, if you aren't a node.js programmer, I wouldn't recommend jumping in and creating a custom node. There are a lot of things to think about and you could easily do this using a flow.

Hi,  
I'm not a node.js programmer, i use to be an [Labview](https://www.ni.com/fr-fr/shop/labview.html) (small) architect --\> so i prefer graphical programming.

Then you probably don't want to write a custom node unless you want to _become_ a node.js programmer!

To use the `node -e "console.log(require('bcryptjs').hashSync(process.argv[1], 8));" {{payload}}` command, firstly you have to be in the userDir folder. Then the `{{payload}}` part needs to be a valid string for the command.

HAve a look at how to use the exec command and understand that the exec environment in Node-RED isn't the same as from a terminal.

Got to run just now so can't give more info.

Hi,

Sorry i mixed **flow sharing** and **asking help** on a function.

I did some errors in variable.  
Should be ok now here the flow :

[flows(18).json](https://discourse.nodered.org/uploads/short-url/nQH1iWeboTkXwHxUgwUwpS0Y7On.json) (51.7 KB)

Did you had an expert look of my flow ?  
I'm not expert in node.js, but i try to be one in NR 😉

Regards.
