fs.rename(oldPath, newPath, callback)

• oldPath <string> | <Buffer> | <URL>
• newPath <string> | <Buffer> | <URL>
• callback <Function>
  • err <Error>

将 oldPath 处的文件异步重命名为作为 newPath 提供的路径名。 如果 newPath 已经存在，则它将被覆盖。 如果 newPath 是目录，则会引发错误。 除了可能的异常之外，没有为完成回调提供任何参数。

另见: rename(2)。

fs.rename('oldFile.txt', 'newFile.txt', (err) => {
  if (err) throw err;
  console.log('Rename complete!');
});

• oldPath <string> | <Buffer> | <URL>
• newPath <string> | <Buffer> | <URL>
• callback <Function>
  • err <Error>

Asynchronously rename file at oldPath to the pathname provided as newPath. In the case that newPath already exists, it will be overwritten. If there is a directory at newPath, an error will be raised instead. No arguments other than a possible exception are given to the completion callback.

  console.log('Rename complete!');
