Remove readonly attribute of windows file in gulp file

Question

How to remove readonly attribute from all files in a folder in Windows?

UPDATE : The question is how to remove the readonly attribute using gulpfile

Answer 1

I understood the answer:

To remove the readonly attribute of all files in a directory recursively, we run the following command in Windows Command Prompt

attrib -r <dir-name>\*.* /s

The next gulp task removes the readonly attribute of all files in

gulp.task('remove-readonly-attributes', function() {
    require("child_process").exec("attrib -r <dir-name>\*.* /s");
});

I decided to solve this problem with gulp -chmod.
