Has `code` property containing last command exit code when available\n - `stdout {String|NULL}` - aggregated stdout or `NULL` if not available\n - `stderr {String|NULL}` - aggregated stderr or `NULL` if not available\n\n**Return Values:**\n\nReturns [ChildProcess](http://nodejs.org/api/child_process.html#child_process_class_childprocess) object.\n\n## Private API\nComplete API Documentation including private and public methods is generated from source code by JSDoc tool and is [available here](https://s3.eu-central-1.amazonaws.com/tsertkov-artifacts/exec-sh/master/jsdoc/index.html).\n\n## Code Coverage\nCode coverage report for all files is [available here](https://s3.eu-central-1.amazonaws.com/tsertkov-artifacts/exec-sh/master/coverage/lcov-report/index.html).\n\n## Scripts\n\n- `npm test` - run tests\n- `npm run jsdoc` - build jsdoc\n- `npm run dev` - run tests continuously\n\n## License\n\nThe MIT License (MIT)\n",
