In addition to hosting Drupal sites, we also host a number of WordPress sites. Similar to checking all of our Drupal core versions, we needed an easy way to quickly see what versions we are running on all of our WordPress sites. Kudos to Ethan for getting this one kicked off; here is a bash script to check your definable $WEBHOME (where you deposit all of your WordPress webroots) and scan for WordPress versions.

At EchoDitto, we host a lot of Drupal sites. Just about all of our web servers contain more than one completely separate Drupal cores since we develop most of our websites independently. We also keep an eye out on Drupal Security and when to apply core updates. Since we're not using Aegir, nor do we run every site off of a single multi-site core install, we need a quick and easy way to see what versions we're running.

After working on some 50-odd Drupal projects over the past few years and inheriting a number of (often questionable) others, it occurred to us it'd be a good idea to have a script that detects hacks and/or "modifications" to Drupal core for a given Drupal install. The result is this remedial PHP script (or core agent) that detects your version of Drupal, downloads the appropriate tarball from Drupal.org, runs a diff on /modules, /misc and /includes, and returns you the results.
