is_category( array( 9, 'blue-cheese', 'Stinky Cheeses' ) )

    Returns true when the category of posts being displayed is either term_ID 9, or slug "blue-cheese", or name "Stinky Cheeses".

in_category( '5' )

    Returns true if the current post is in the specified category id. read more in_category( array( 1,2,3 ) )
    Returns true if the current post is in either category 1, 2, or 3.

! in_category( array( 4,5,6 ) )

    Returns true if the current post is NOT in either category 4, 5, or 6. Note the ! at the beginning.

h4hardy - Thanks for the reply, but my knowledge of php / wordpress is not great.

How can I combine with the below...

<?php while ( have_posts() ) : the_post(); ?>

<?php get_template_part( 'content', get_post_format() ); ?>

<?php endwhile; ?>

I want to show all posts except in the category with the slug name "blogs".

How do I do that?

From: http://codex.wordpress.org/The_Loop#Exclude_Posts_From_Some_Category

To exclude a category, just add query_posts above the loop and put the category ID to be excluded with a -

 <?php query_posts($query_string . '&cat=-3,-8'); ?>
 <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>

 <div class="post">
 
 <!-- Display the Title as a link to the Post's permalink. -->
 <h2><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></h2>

 <!-- Display the date (November 16th, 2009 format) and a link to other posts by this posts author. -->
 <small><?php the_time('F jS, Y') ?> by <?php the_author_posts_link() ?></small>
 
  <div class="entry">
    <?php the_content(); ?>
  </div>

  <p class="postmetadata">Posted in <?php the_category(', '); ?></p>
 </div> <!-- closes the first div box -->

 <?php endwhile; else: ?>
 <p>Sorry, no posts matched your criteria.</p>
 <?php endif; ?>
