My objective is to run a node.js CLI inside my devcontainer. I want to copy some text to the host clipboard inside the container.

This was super simple before running in a devcontainer, because on Mac OS I could call pbcopy like this:

import { exec } from 'node:child_process';
const child = exec(command);

    if (child.stdin) {
        child.stdin.end(text); // This sends the text to the command's stdin
    }
}

But this does not work in devcontainers. Tried with xclip but get:

Authorization required, but no authorization protocol specified
Error: Can't open display: :1

Did anyone manage to get this to work?
