Adding author on blog roll

What is shortened blogroll?

Sorry, it is the ‘Display Post Excerpts’

When I use this feature it shows my posts starting with the word by (then the post text follows). Is there a way of adding the author name next to the word by ? before the post text starts?

This happens for every excerpt post on the roll.

Hope this makes sense.

“by Author” will appear only if you have more than 1 Author. You can find and modified the code (child theme is recommended) in /partials/entry-byline.php

<div class="entry-meta">
	<time <?php omega_attr( 'entry-published' ); ?>><?php echo get_the_date(); ?></time>
	<span <?php omega_attr( 'entry-author' ); ?>><?php echo __('by ', 'omega'); the_author_posts_link(); ?></span>
	<?php echo omega_post_comments( ); ?>
	<?php edit_post_link( __('Edit', 'omega'), ' | ' ); ?>
</div><!-- .entry-meta -->

Thank you for your reply. Unfortunately, I have no idea how to write or amend code. Is there a simple way of doing this for a complete novice?
