File | Settings | Command Line Tool Support
The dialog box opens when you click the Add button and choose Drush in the Choose Tool to Add dialog box. Use the dialog box to configure Drush support in IntelliJ IDEA.
Drush is a command line shell and scripting interface for Drupal. With IntelliJ IDEA, you can use Drush 5.8 and higher. For more details, see Using Drupal with IntelliJ IDEA and Drupal-Specific Coding Assistance.
|Path to Drush||In this text box, specify the path to the Drush executable file. IntelliJ IDEA automatically fills in the default location, which is usually C:/ProgramData/Drush/drush.bat on Windows and /usr/bin/drush on Mac OS or Linux. If you followed the standard installation procedure, the predefined path will be correct, just click OK, whereupon IntelliJ IDEA loads command definitions automatically and returns to the Command Line Tool Support page.|
