@ariporad : It requires a lot of boilerplate code to create a common ssh client with mscdex/ssh2 as you have to handle output, input and error streams.

// Interactive shell client
const client = new Client();
client.on('ready', () => {
  client.shell((err, stream) => {
    if (err) throw err;
    // Piping
    process.stdin.setRawMode(true);
    process.stdin.pipe(stream);
    stream.pipe(process.stdout);
    stream.stderr.pipe(process.stderr);

    stream.on('close', () => {
      // Release stdin
      process.stdin.setRawMode(false);
      process.stdin.unpipe(stream);
       // End connection
       client.end();
    });
  });
});

// Exec a command over ssh
const cmd = 'pwd';
const client = new Client();
client.on('ready', () => {
  client.exec(cmd, (err, stream) => {
    if (err) throw err;
    stream.pipe(process.stdout);
    stream.stderr.pipe(process.stderr);
    stream.on('close', () => {
      client.end();
      end();
    });
  });
});

The idea is to abstract it to allow the user to only type a single command like other shelljs commands.
