Batch update modules or themes of Drupal 6/7 in command line

To update Drupal modules, you need to download manually all modules and this can quickly become tedious. Especially if you have multiple modules and Drupal installations.

I wrote a simple script that parse the module’s page and install or update the most up-to-date version.

This works for themes as well. To use it, simply go into a modules or themes folder and run one of the tool.

Valid folders are:

• /modules
• /themes
• /sites/all/modules
• /sites/all/themes
• /sites/*/modules
• /sites/*/themes

However, not that you should not try to update root folders, they are reserved for core modules and are updated with Drupal.

drupal-install-module.sh will install or update one module, drupal-update-modules.sh will batch update all modules in current folder.

# drupal-install-module.sh
#!/bin/bash

# Usage: drupal-install-module.sh module [6|7]
# Installs module to most up-to-date version. Updates if already present
# Specifiy Drupal version 6 or 7
# Works with themes as well
# You must go to /update.php to complete the process afterwards
