The regular expression to effectively detect hidden files and directory path in Unix would be a bit more complex owing to the possibility of their existence within a long path string.

The following tries to take care of the same.

/**
 * Checks whether a path starts with or contains a hidden file or a folder.
 * @param {string} source - The path of the file that needs to be validated.
 * returns {boolean} - `true` if the source is blacklisted and otherwise `false`.

var isUnixHiddenPath = function (path) {
    return (/(^|\/)\.[^\/\.]/g).test(path);
};
