Question

This question, has an accepted answer that only redirects the out “command” to an output stream. I would like to redirect all the output from a script to a stream, not just a subset of the output that is created with out << "hello world" commands.

This answer changes the script to write all its output via out “command”. Is there a solid solution that does’t require changing the script?

Answer 1

You can bind System.out to another stream, like (if you’re calling it from plain Java):

PrintStream ps = new PrintStream(new FileOutputStream("console.out"));
System.setOut(ps);
//call your script there

or more groovier:

System.out = new File('console.out').newPrintWriter()
//call your script there
