I'm developing now a wordpress theme, and wondering if there is an option to know if a template file is being used by a page? I need the link to that page... thanks!

The function get_page_template_slug( $post_id ) will return the slug of the currently assigned page template (or an empty string if no template has been assigned - or false if the $post_id does not correspond to an actual page). You can easily use this anywhere (in The Loop, or outside) to determine whether any page has been assigned a page template.
is_page_template(); function will return true when template is used. you can also pass file name to check if particular template is applied or not.
if ( is_page_template('about.php') ) {
// Returns true when 'about.php' is being used.
} else {
// Returns false when 'about.php' is not being used.
}There is one more method too. You can use get_post_meta to get value of applied template.
global $post;
get_post_meta($post->ID,'_wp_page_template',true);The previously suggested answer will not get you what you want. It will just show you in the current page or a page you specify is using the template not find any pages that are using it.
If you want to actually search to see if any pages are using a template you can make a query. meta_query isn't the most efficient/fastest but depending on what you are building probably won't be an issue.
$query = new WP_Query( array( 'post_type' => 'page', 'post_status' => 'publish', 'meta_query' => array( array( 'key' => '_wp_page_template', 'value' => 'your-template.php', ), ), ) );
if ( $query->have_posts() ) { /* There is a match so either start the loop and use get_the_permalink() to get the link or make a foreach loop and get the ids of the items and get_the_permalink($id) */
}
