Make the author link on meta go to buddypress profile

Hi @Sakin I want to link all the author links on metas go to the buddypress profile. I am using a child theme of catch box pro. I managed to to this only at the end of the post where the categories, tags and author is displayed changing get_the_author for bp_core_get_userlink( $post->post_author ) in content-single.php. However i can´t find the get_the_author() function in content and content-single.php to make the author link on after title meta go to profile. Where should i search for it? Thanks in advance
