The lchown function has the following signature:

index.ts
function lchown(path: PathLike, uid: number, gid: number): Promise<void>;
74 chars
2 lines

Where path is the path of the file or directory to modify the ownership of, uid is the new user ID, and gid is the new group ID.

Here's an example of how to use it in TypeScript:

index.ts
import { lchown } from 'fs-extra';

async function changeOwnership() {
  try {
    await lchown('/path/to/file.txt', 1000, 1000);
    console.log('Ownership changed successfully!');
  } catch (err) {
    console.error(err);
  }
}

changeOwnership();

This code will change the ownership of /path/to/file.txt to the user ID 1000 and the group ID 1000. The function returns a Promise that can be awaited to know if the operation was successful or not.
