Script to get a diff of a Drupal dev project from git and write the diff to the projects folder: `bash check_hacked.sh $PROJECTNAME`.

Check hacked status from git

This small script provides some code to check a project of your installation (located in .../www) against the associated git commit on drupal.org.

Notice: currently the root path and temp directory are hardcoded.

Examples

Check status of views module.

bash drupal_hackedgit.sh views
