I have 2 blogs, one which is multisite and one which isn't. I want to get a list of plugins active on both the blogs so I can compare them. On the multisite blog, I want to list the plugins which are enabled network-wide as well as site wide.

The activated plugins are stored in the options table of a WordPress Blog under the key active_plugins

so you can use get_option('active_plugins'); of each blog and compare the arrays.

    It's worth adding that get_plugins() will give you all the plugins including the inactive ones. – Charles Jaimet Nov 27 '14 at 19:46

In form of a Dashboard Widget, one for Single Sites and Network Sites Dashboard, other for the Multisite Network Dashboard.

/*
 * Single Site Dashboard Widget
 */
add_action('wp_dashboard_setup', 'wpse_54742_wp_dashboard_setup');

function wpse_54742_wp_dashboard_setup() {
    wp_add_dashboard_widget( 'wpse_54742_active_site_plugins', __( 'Active Plugins' ), 'wpse_54742_active_site_plugins' );
}

function wpse_54742_active_site_plugins() {
    $the_plugs = get_option('active_plugins'); 
    echo '<ul>';
    foreach($the_plugs as $key => $value) {
        $string = explode('/',$value); // Folder name will be displayed
        echo '<li>'.$string[0] .'</li>';
    }
    echo '</ul>';
}


/*
 * Multisite Dashboard Widget
 */
add_action('wp_network_dashboard_setup', 'wpse_54742_network_dashboard_setup');

function wpse_54742_network_dashboard_setup() {
    wp_add_dashboard_widget( 'wpse_54742_active_network_plugins', __( 'Network Active Plugins' ), 'wpse_54742_active_network_plugins' );
}

function wpse_54742_active_network_plugins() {
    /*
     * Network Activated Plugins
     */
    $the_plugs = get_site_option('active_sitewide_plugins'); 
    echo '<h3>NETWORK ACTIVATED</h3><ul>';
    foreach($the_plugs as $key => $value) {
        $string = explode('/',$key); // Folder name will be displayed
        echo '<li>'.$string[0] .'</li>';
    }
    echo '</ul>';


    /*
     * Iterate Through All Sites
     */
    global $wpdb;
    $blogs = $wpdb->get_results($wpdb->prepare("
        SELECT blog_id
        FROM {$wpdb->blogs}
        WHERE site_id = '{$wpdb->siteid}'
        AND spam = '0'
        AND deleted = '0'
        AND archived = '0'
    "));

    echo '<h3>ALL SITES</h3>';

    foreach ($blogs as $blog) {
        $the_plugs = get_blog_option($blog->blog_id, 'active_plugins'); 
        echo '<hr /><h4><strong>SITE</strong>: '. get_blog_option($blog->blog_id, 'blogname') .'</h4>';
        echo '<ul>';
        foreach($the_plugs as $key => $value) {
            $string = explode('/',$value); // Folder name will be displayed
            echo '<li>'.$string[0] .'</li>';
        }
        echo '</ul>';
    }
}

List of plugins, with sites on which they are used (Multisite only)

If you want to know which plugin is currently activated and on which site, you can use a function like that one:

function wpstars_list_active_plugins() {

  if ( function_exists( 'get_sites' ) && class_exists( 'WP_Site_Query' ) ) {

    echo "<table class='active-plugins'>";
    echo "<tr><th>Plugin name</th><th>Sites</th></tr>";

    $plugins = get_plugins();

    // Network activated
    $active_plugins = get_site_option('active_sitewide_plugins');
    foreach($active_plugins as $active_path => $active_plugin) {

      $plugins[$active_path]['Sites'] = "A,";
    }

    // Per site activated
    $sites = get_sites();
    foreach ( $sites as $site ) {

      $active_plugins = get_blog_option($site->blog_id, 'active_plugins');
      foreach($active_plugins as $active_plugin) {

        $plugins[$active_plugin]['Sites'] .= $site->blog_id . ",";
      }
    }

    foreach($plugins as $plugin) {

      echo "<tr><td>{$plugin['Name']}</td><td>{$plugin['Sites']}</td></tr>";
    }

    echo "</table>";
  }
}

WP-CLI is just the ticket. I've used if for so many things, I've lost count!

wp plugin list --status=active

If you want, you can run these commands on your local machine with aliases...

You would then use the @site function

wp @all plugin list --status=active

or

wp @multisite list --status=active
wp @blog list --status=active
