How to perform a series of commands?

I'm wondering how I could use this module for running a series of conditional ssh commands. For example:

var folder = "example";
exec('cd ' + folder, 'ubuntu@my-remote.com', function (err, stdout, stderr) {
  if(stdout.indexOf("No such file or directory") {
    exec("mkdir " + folder, 'ubuntu@my-remote.com', function (err, stdout, stderr) {

    });
  }
  exec("do something", "ubuntu@my-remote.com", function (err,stdout,stderr) {

  });
})

Is this a valid approach? Is it necessary to provide the credentials for every command? Any suggestions?

Start with the module's exec API and the command sequence shown in the issue. Determine how conditional commands and SSH credentials are intended to work, then document the supported usage and limitations. Done means the guidance answers whether this approach is valid and whether credentials are needed for each command.
