How do I redirect all subdomains of example.com from http to https using .htaccess?

I've searched Google and can't find a solution.

To redirect all subdomains of example.com to https , you can use :

RewriteEngine on
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} ^((?!www\.)[^.]+)\.example\.com$
RewriteRule ^ https://%1.example.com%{REQUEST_URI} [NE,L,R]
