WordPress Theme change metadata - php

Question

How can I edit the Php file for a Wordpress theme (shape - downloaded from themeshaper.com) to change the metadata.
for example current php file below displays the meta of a normal post like this:
for example instead of [avatar] [author] written on [date] like in the image above, I would like to change to Posted on [date] by [author].
Php File (content.php):
<?php
/**
* #package Shape
* #since Shape 1.0
*/
?>
<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
<header class="entry-header">
<!-- header content -->
<h1 class="entry-title"><?php the_title(); ?></h1><?php if ( 'post' == get_post_type() ) : ?>
<div class="entry-meta">
<?php shape_posted_on(); ?>
</div><!-- .entry-meta -->
<?php endif; ?><!-- end header content -->
</header><!-- .entry-header --><?php if ( is_search() ) : // Only display Excerpts for Search ?>
<div class="entry-summary">
<?php the_excerpt(); ?>
</div><!-- .entry-summary -->
<?php else : ?>
<div class="entry-content">
<?php the_content( __( 'Continue reading <span class="meta-nav">→</span>', 'shape' ) ); ?>
<?php wp_link_pages( array( 'before' => '<div class="page-links">' . __( 'Pages:', 'shape' ), 'after' => '</div>' ) ); ?>
</div><!-- .entry-content -->
<?php endif; ?> <footer class="entry-meta">
<!-- footer content -->
<?php if ( 'post' == get_post_type() ) : // Hide category and tag text for pages on Search ?>
<?php
/* translators: used between list items, there is a space after the comma */
$categories_list = get_the_category_list( __( ', ', 'shape' ) );
if ( $categories_list && shape_categorized_blog() ) :
?>
<span class="cat-links">
<?php printf( __( 'Posted in %1$s', 'shape' ), $categories_list ); ?>
</span>
<?php endif; // End if categories ?> <?php endif; // End if 'post' == get_post_type() ?> <?php if ( 'post' == get_post_type() ) : // Hide category and tag text for pages on Search ?>
<?php
/* translators: used between list items, there is a space after the comma */
$tags_list = get_the_tag_list( '', __( ', ', 'shape' ) );
if ( $tags_list ) :
?>
<span class="sep"> | </span>
<span class="tag-links">

Answer 1

I know it is late to answer but something like this will work if anyone else is interested
<p class="postmetadata">
<?php _e('Filed under:','domain'); ?>
<?php the_category(', ') ?> <?php _e('by','domain'); ?> <?php the_author(); ?>
<br/><?php the_tags(__('Tags:','domain'), ', ', '<br />'); ?>
<?php _e('Posted on: ','domain'); ?>
<?php the_time(get_option('date_format')); ?><br/>?>
<?php edit_post_link(__(' Edit','domain'), __(' |','domain'), ''); ?>
</p>
