Change file ownership (does not resolve symbolic links).

Grammar:

Copy code The code is as follows:

fs.lchown(path, uid, gid, [callback(err)])

callback Callback, passing the exception parameter err

Example:

Copy code The code is as follows:

fs.lchown('content.txt', uid, gid, function(err){

if(err){

console.log(err);

}else{

console.log("change done");

}

})
