The default method of changing a Drupal theme using the graphical Admin interface is familiar to most Drupal users. However a Drupal user is limited to changing only one theme at a time using this method and it is also slightly time consuming. What if you want to enable more then one theme at a time? Drupal provides a quicker way to change the theme using the bash command line. Read on to know how to enable multiple Drupal themes using the bash command line

  1. First we have to install drush on your server. Drush is a command line interface for accessing and working with Drupal
  2. After installing Drush lets check out all the existing themes in our Drupal site
  3. Type the following command from your Drupal server
    ~/drush/drush pm-list --type=theme
  4. In sites/all/themes folder type
    drush pm-list --type=theme
  5. This will display all themes in following order
  • Package
  • Name
  • Status
  • Version

To enable a single theme with confirmation

  1. Type the following command from your Drupal server
    ~/drush/drush pm-enable themename
    eg: ~/drush/drush pm-enable vert

  2. In sites/all/themes folder type
    drush pm-enable themename
    eg: drush pm-enable business_blog

To enable a single theme without confirmation

  1. Type the following command from your Drupal server
    ~/drush/drush pm-enable themename --yes
    eg: ~/drush/drush pm-enable vert --yes

  2. In sites/all/themes folder type
    
    drush pm-enable themename --yes
    eg: drush pm-enable black_blog --yes

List all themes with the associated info

  1. Type the following command from your Drupal server
    ~/drush/drush pm-list --type=theme | tr -s ' '
  2. In sites/all/themes folder type
    drush pm-list --type=theme | tr -s ' '

Cut each column

  1. Type the following command from your Drupal server
    ~/drush/drush pm-list --type=theme | tr -s ' '| cut -f1 -d' '
    ~/drush/drush pm-list --type=theme | tr -s ' '| cut -f2 -d' '~/drush/drush pm-list --type=theme | tr -s ' '| cut -f3 -d' '
    
  2. In sites/all/themes folder type
    drush pm-list --type=theme | tr -s ' '| cut -f1 -d' '
    drush pm-list --type=theme | tr -s ' '| cut -f2 -d' '
    drush pm-list --type=theme | tr -s ' '| cut -f3 -d' '

Display all theme names

  1. Type the following command from your Drupal server
    ~/drush/drush pm-list --type=theme | tr -s ' ' | sed s/.*\(//| sed s/\).*//
    
  2. In sites/all/themes folder type
    drush pm-list --type=theme | tr -s ' ' | sed s/.*\(//| sed s/\).*//

Write all the themes to a themelist file

  1. Type the following command from your Drupal server
    ~/drush/drush pm-list --type=theme | tr -s ' ' | sed s/.*\(//| sed s/\).*// > themelist
  2. In sites/all/themes folder type
    drush pm-list --type=theme | tr -s ' ' | sed s/.*\(//| sed s/\).*// > themelist
  3. Make sure that the file contains only theme name and not any other content. You can edit the file using following commands
    less themelist
    nano themelist
    wc -l themelist

Display all the themes from themelist file

  1. for i in `cat themelist`; do  echo $i; done
    

Enable all the themes (with confirmation required)

  1. Type the following command from your Drupal server
    for i in `cat themelist`; do  ~/drush/drush en $i; done
  2. In sites/all/themes folder type
    for i in `cat themelist`; do  drush en $i; done

Enable all the themes (without confirmation)

  1. Type the following command from your Drupal server
    for i in `cat themelist`; do  ~/drush/drush en $i --yes; done
  2. In sites/all/themes folder type
    for i in `cat themelist`; do  /drush en $i --yes; done

Search for stumblethis_button and you should be able to see the code for the image and the URL. Then you should be able to troubleshoot from there.

Most webmasters do not realize this, but a lot of the content on lot of websites can be accessed from multiple URLs. A simple example would be where www.example.com and example.com leads to the same page. This is a fatal mistake in Search Engine Optimization and search engines penalize you for duplicate content. The correct configuration would be where the above two urls will lead you to the same page but example.com will redirect you to www.example.com with a 301 (Moved permanently) status which will not result in search engines penalizing the page. It is very easy to configure 301 redirects using Apache .htaccess file and the process is the same for a Drupal installation also.

I'm trying to make example.com show as www.example.com, and I'm running into difficulties. I'm on Apache 2.0 and using the following lines in my httpd.conf file: RewriteEngine on RewriteCond %{HTTP_HOST} ^xxxxxxxxxx\.com$ [NC] RewriteRule ^(.*)$ http://www.xxxxxxxxxx.com/$1 [L,R=301] When I go to http://xxxxxxxxxx.com, I get http://www.xxxxxxxxxx.com (as expected). However, when I go to http://xxxxxxxxxx.com/node/1 (it's a Drupal site), I get a 404 thrown and the URL changes to xxxxxxxxxx.com/var/www/drupal/node/1. Same thing with www.xxxxxxxxxx.com/node/1. Any suggestions? I want to run without Drupal's .htaccess file (instead incorporating these calls into my httpd.conf file). webmaster access_time 18 Jul 2019 - 22:01 In reply to Rewrite including filesystem path by Anonymous (not verified) I think the problem is with the base path which results in the redirection to /var/www/ part. The best approach I would think is to start with drupal htaccess and then strip out parts and move to httpd SNVC (not verified) access_time 18 Jul 2019 - 22:01 This is definitely a good guide. Thanks for this. wellyson access_time 18 Jul 2019 - 22:01 This is really nice and helpful. Add new comment

We have volunteered to take up the maintenance of a very useful Drupal module - Search404. As of today we are the official maintainers of this very useful Drupal module. We know that this is going to be a challenge for us, being a young company and with a young team. But we do feel that it is our responsibility to give back to the Drupal community at least some part of what it has given us.

Do you have any expectation on when a version for Drupal 6 will be ready? webmaster access_time 18 Jul 2019 - 22:01 In reply to when will search404 for drupal 6 be ready? by ian douglas (not verified) Hi Ian, We are currently working on moving Search404 to Drupal 6. The port has already been done and we should have a release up on drupal.org by tomorrow or worst case by monday.
