Use Bun.spawn() to spawn a child process. 
const proc = Bun.spawn(["echo", "hello"]);

// await completion
await proc.exited;
The second argument accepts a configuration object. 
const proc = Bun.spawn(["echo", "Hello, world!"], {
  cwd: "/tmp",
  env: { FOO: "bar" },
  onExit(proc, exitCode, signalCode, error) {
    // exit handler
  },
});
By default, the stdout of the child process can be consumed as a ReadableStream using proc.stdout. 
const proc = Bun.spawn(["echo", "hello"]);

const output = await proc.stdout.text();
output; // => "hello\n"
