Executing a command by javascript when clicking on a link

Is there a way to make the following work without having to manually press enter? I need this to make a small automation tool.

<div id="terminal-container"></div>
<div id="commands">
    <a href="javascript:exec('ls -la');">ls -la</a>
    <a href="javascript:exec('sudo su');">sudo su</a>
</div>
<script>
function exec(cmd) {
    term.send(cmd); // needs manual Enter
    term.write(cmd); // also needs manual Enter
    term.writeln(cmd); // although the cursor advances to the next line, the command does not get executed
}
</script>

I have searched the issues and the closest thing I found was this comment offering this method:

process.send({
  event: 'input',
  data: text
});

But where is process exposed? It does not seem to be accessible thorough term.

You need to write it to node-pty, not xterm.js. You’re trying to simulate an xterm.js onData event which would be forwarded to node-pty, so call whatever you’re using in your onData event handler.

Key presses: xterm.js -> node-pty Process data: node-pty -> xterm.js

@Tyriar Used pty.write(“\r”) and was able to execute the commands
