You can use various methods to check the Drupal version of your project. Here are the different ways to determine the Drupal version across platforms and tools, including Drush, the admin interface, and different local development environments like Docksal, Lando, and DDEV.

1. Using Drush

Drush is a command-line utility for managing Drupal.

drush status

Look for the line that shows:

Drupal version: 10.x.x

This command works across all platforms where Drush is installed.

Alternative Drush Command:

If you have Drush 9+ installed, use:

drush core-status --field=drupal-version

This will only output the Drupal version directly.

2. Through the Admin Interface

You can check the version directly from the Drupal admin UI.

Go to Admin > Reports > Status report:

URL: /admin/reports/status

On this page, you'll find a line called Drupal version that shows the current version.

3. Check CHANGELOG.txt

Another way to find the Drupal version is by checking the CHANGELOG.txt file.

Path:

[Drupal project root]/core/CHANGELOG.txt

The first few lines of this file will indicate the version.

4. Using Composer

If your project uses Composer (common for Drupal 8 and later), you can check the Drupal version with Composer.

composer show drupal/core | grep versions

This will output something like:

versions : * 10.x.x

5. In Codebase: Check core/lib/Drupal.php

You can check the version in the core PHP file.

Open the file:

[Drupal project root]/core/lib/Drupal.php

Look for the constant:

const VERSION = '10.x.x';

6. Environment-Specific Ways

Docksal

fin drush status

Alternatively, run Composer commands within Docksal:

fin composer show drupal/core | grep versions

Lando

lando drush status

Or, using Composer:

lando composer show drupal/core | grep versions

DDEV

ddev drush status

Or, using Composer:

ddev composer show drupal/core | grep versions

7. Using Web Browser

If you don’t have access to the command line but can access the website:

Visit the /core/misc/drupal.js URL.

Search for a comment line at the top that may indicate the version, though this isn't always reliable due to caching or access restrictions.

8. Using Database Table (key_value)

If you have direct access to the database:

SELECT value FROM key_value WHERE collection = 'system.schema' AND name = 'system';

It will show the major version of Drupal.

9. Checking Version on Pantheon, Acquia, or Other Hosting Platforms

• Pantheon: You can use the Pantheon Dashboard to check the Drupal version.
• Acquia: Use the Acquia Cloud UI or the Acquia CLI with Drush commands to check the version.
• For other platforms, you might use SSH access to run Drush commands directly.
