Migrating from Deno.run to Deno.command, how to readLines?

At the moment I have this:

const command = new Deno.command('...');
for await (const line of readLines(command.stderr!)) {
  // ...
  break;
}

// .. Continue using sun process

const command = new Deno.command('...');
for await (const line of readLines(command.stderr!)) {
  // ...
  break;
}

// .. Continue using sun process

How would I now do this if using Deno.Command? I'm currently spawning a long running subprocess that doesn't exit on it's own, so simply running the command, and using outputSync() probably isnt an option

Migrating `Deno.run` to `Deno.command` with `readlines`

I had the following:

 browserProcess = Deno.run({
  cmd: buildArgs, // eg chrome exe path, then options
  stderr: "piped",
  stdout: "piped",
});
for await (const line of readLines(browserProcess.stderr!)) {

 browserProcess = Deno.run({
  cmd: buildArgs, // eg chrome exe path, then options
  stderr: "piped",
  stdout: "piped",
});
for await (const line of readLines(browserProcess.stderr!)) {

Now i'm wondering what the best way to do this with Deno.command is?

Can I programatically trigger a SIGINT event?

I would like to trigger a SIGINT event from a file, is there a way to do this? For example in Node, you can do process.emit('sigint');
