write to process without echo-ing the message

[dusadrian]

Hello, newbie here.
Would it be possible to send a message (command) to a process, but without displaying that command in the terminal (such as xterm.js)?

Ideally, it should also receive a response.

It should not be write (which echoes in the terminal), but presumably something else. Something in the direction of:
console.log(ptyProcess.write('ls\r'));

(thus receiving the result in the Javascript caller)
Thanks in advance.

Other than something like this, the only way to do something like this is to intercept the data stream and remove characters from it before it gets to your terminal.

Thanks very much, this helps a lot.
The way to intercept the data stream resides in the renderer.js file, in this call:

ptyProcess.on('data', function (data) {
  xterm.write(data);
});

Awesome.
