NodeJS synchronous exec: printing output to console vs returning output from function

execSync.js

function execSyncPrintOutput(command, env) {
  env = env || process.env;
  try {
    return require('child_process').execSync((command), {
      stdio: 'inherit',
      env: env
    });
  } catch (e) {
    __handleExecFailure(command);
  }
}

function execSyncReturnOutput(command, env) {
  env = env || process.env;
  try {
    return require('child_process').execSync((command), {
      stdio: 'pipe',
      env: env
    }).toString();
  } catch (e) {
    __handleExecFailure(command);
  }
}
