run Linux command from a mm2 module

You can use Regular Expression for getting matched text with pattern.

var s = stdout
var fan1 = new RegExp("fan1\:\s+([0-9]+ RPM)")
var fan1_found = s.match(fan1)
console.log(fan1_found, fan1_found[1])

Not tested in real PC, so there could be a mistake.

First, thank you for your input. I do appreciate it.

1. Adding your suggestion results in an uncaught exception. . . TypeError: Cannot read property ‘1’ of null

2. Using your suggestion and taking out the “[1]” results in an array with a single object

null means not found. Maybe my regular espression pattern was wrong. As I wrote, it was not tested.
However if you find proper expression pattern, it will return matched string. Google it about regular expression. That is a standard way to search or replace text by pattern in most of program languages.

@sean

ok thank you. This seems like a good place to start.

let me see what I can do.
Will be tomorrow.

Thanks! Anything you can offer will be much appreciated.

This what I have, and sent to the module.js

Excellent sean! Working here as well. You have my eternal gratitude. :thumbsup:

EDIT

Using your example above as a guide I was able to add to the pattern array successfully.

My addition
"(Core [0-9]):[\\s]+(\\+[0-9\\.]+°C)"

Result

Now I’ll do the ones I want. Thank you again, sean. This is awesome!

@mykle1 @sean nice work. Sorry I ran out of time.

@sdetweil

No worries, bro. I appreciate your interest and concern. I’m sure I’ll need help in the future. You can get in on that. :-)
