Drush (short for Drupal Shell) is a command-line tool and scripting interface specifically designed for Drupal, a popular content management system (CMS). It provides a convenient way for developers, site administrators, and Drupal power users to manage and automate various tasks related to Drupal websites.
Here are key features and aspects of Drush:
- Command-line interface: Drush allows you to interact with Drupal websites through a command-line interface (CLI). It provides a set of commands that you can execute directly from the terminal, eliminating the need for repetitive manual tasks in the Drupal administration interface.
- Site management: With Drush, you can perform a wide range of site management tasks. This includes installing Drupal, updating modules and themes, enabling or disabling modules, managing user accounts, clearing caches, running database updates, and much more. These operations can be performed on individual sites or across multiple sites within a Drupal multisite installation.
- Batch operations and automation: Drush makes it easy to perform batch operations and automate repetitive tasks. You can write custom scripts or commands using Drush’s scripting interface to automate tasks such as site backups, deployment, configuration management, and other site-specific operations.
- Drush extensions: Drush supports extensions in the form of commands and plugins, allowing you to extend its functionality. You can install contributed Drush extensions, such as additional commands or custom modules, to enhance the capabilities of Drush and tailor it to your specific needs.
- Integration with version control: Drush seamlessly integrates with version control systems like Git. It provides commands to manage Drupal sites within a version-controlled workflow, allowing you to deploy changes, synchronize database updates, and revert configuration changes more efficiently.
- Remote server management: Drush enables you to manage Drupal websites hosted on remote servers. You can execute commands on remote servers, sync files and databases between local and remote environments, and perform other administrative tasks without directly accessing the server.
- Drupal site aliasing: Drush utilizes site aliases, which are configuration files that define connections to Drupal sites. Site aliases allow you to quickly switch between different Drupal installations, making it easy to manage multiple sites from a single command line.
Drush is a powerful tool that significantly enhances the productivity of Drupal developers and site administrators. It provides a convenient and efficient way to perform common Drupal tasks, automate workflows, and manage Drupal websites from the command line. Drush is actively maintained and widely used within the Drupal community.
