Hi Chris,

‘fs’ module is a part of Node.js, which is an extension of core JavaScript language. Our JavaScript engine only supports core language features, so ‘fs’ module cannot be used.

We also do not support ‘console’ since this is not a part of the core JavaScript language, but rather a browser addition.

We do provide alternatives though:

• With the release of Android JavaScript Engine 1.2 (available since agent’s version 14.5.0), we have our own file system APIs, plus XML parsing support, see https://www.soti.net/mc/help/javascriptapi/en/mobicontrol.io.File.html and https://www.soti.net/mc/help/javascriptapi/en/tutorial-commonTextDataFormats.html
• Instead of console.log use mobicontrol.log.info – this will send the log to the WebConsole as well as to the log journal on the device

 Basically your code will look something like this:

var inputFile = new mobicontrol.io.File(‘/mnt/sdcard/Documents/app/config.txt’);
var data = inputFile.readText();
var result = data.replace(/yahoo.com/g, 'google.com');

var outputFile = new mobicontrol.io.File(‘someFile’);
outputFile.writeText(result);

If there is any error – it will be automatically logged, however if you need a special error handling – you can do so using a try-catch block, see an example in https://www.soti.net/mc/help/javascriptapi/en/mobicontrol.intl.Locale.html

The javascript based scripting options include read/write file access so you should be able to accomplish what you need to there. Javascript is a well established and documented programming language with a lot of reference material online.  

That's kind of what I figured and was playing a bit last night.  I found a snippet that looked like it would do it, but got some errors when sending it to the device.  As I read some more of the javascript reference from Soti, there was mention of having to upload the module into a path on the device before it could be used.  Based on that, where do I find these modules?  I struck out last night.  Below is the script I was attempting to run where in theory it would replace yahoo.com with google.com as an example. 

I would assume that the modules readFile, data.replace, and writeFile would need to be added to the device in order for this to work?

var fs = require('fs')
fs.readFile(/mnt/sdcard/Documents/app/config.txt, 'utf8', function (err,data) {
  if (err) {
    return console.log(err);
  }
  var result = data.replace(/yahoo.com/g, 'google.com');

  fs.writeFile(someFile, result, 'utf8', function (err) {
     if (err) return console.log(err);
  });
});

The error I was getting back:  "Custom log (invalid flag after regular expression (UserScript#2)) "

Hi Chris,

Thank you for posting in SOTI Central.

I've sent a request internally to clarify a few aspects regarding the capabilities of our Android Agent and the JavaScript feature. We'll be in touch in due course.

I did test this today and it worked as expected.  Thanks much for the help!
