I have a script like so:
var target = UIATarget.localTarget();
var mainWindow = target.frontMostApp().mainWindow();
var element = mainWindow.textFields()[\"
Yes it is possible. You can acquire every data that you are able to acquire in a bash script. Write a script file that prints the desired information to the standard output. For example
#!/bin/bash
cat myfile
You can run this bash-script from UIAutomation and get the output of it with this command
var result = target.host().performTaskWithPathArgumentsTimeout(full_path_to_your_script, [""], 10);
Now your can use the output of your bash script:
element.setValue(result.stdout);
