Drupal shell: quickly evaluating PHP statements in a Drupal context
Posted on August 5th, 2008 by Sacha Chua
I often find myself needing to variable_set something temporarily, just to try things out. The drush module provides a command-line interface that solves this problem with a little more hacking. To minimize the effect on my source tree, I’ve unpacked it into the sites directory for my local installation and enabled it in my test database. After I enabled the main drush module and the related modules, I tweaked drush_tools to include an insecure-but-useful eval command. Here it is:

I also added an alias to my ~/.bashrc along the lines of:
alias drush='php ~/drupal/sites/local.example.com/modules/drush/drush.php -r ~/drupal -l http://local.example.com'
where ~/drupal is my multisite Drupal directory root.
After I loaded the alias with “source ~/.bashrc”, I can now execute PHP statements in my Drupal context with commands like:
drush eval "variable_set('hello', 'world');"
Good stuff!

nothing insecure about it. if you can run a drush command you have command line access and thus can do much nastiness. please submit a patch for drush toolbox. this is worthy.

Thanks for posting that! =) It took me a while to get work permission to contribute to Drupal, but I now have it – hooray!
