Book description

A practical guide to Drush, Drupal’s command line interface, helping you work with your Drupal sites more effectively with this book and ebook.

  • Stop clicking around administration pages and start issuing commands straight to your Drupal sites.

In Detail

Drush is a command line interface for Drupal. Most of the tasks for building and maintaining a website are repetitive and involve filling in forms on administration pages. The majority of these tasks can be achieved with a single Drush command, shortening the development and maintenance time of a project drastically.

Drush User’s Guide will allow you to be more productive and efficient in building and maintaining your Drupal sites through the command line. You will learn to install Drush on different platforms, and manage and configure your Drupal site by learning how to use and create Drush commands.

Become a Drush expert by exploring its command toolkit; customizing it to suit your needs, and extending it with contributed modules.

The command line will allow you to download, enable and upgrade Drupal projects in seconds. Back up your files, code and data in one single file, clear the cache, interact with databases, and deploy sites to remote machines – all using simply the command line. Use Drush with your own commands or alter existing ones; and extend the toolkit with a long list of contributed modules.

Drush User’s guide has everything you need to extend your use of the command line to easily build and manage your Drupal sites.
