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 PhpStorm.
Drush is a command line shell and scripting interface for Drupal. With PhpStorm, you can use Drush 5.8 and higher. For more details, see Using Drupal with PhpStorm and Drupal-Specific Coding Assistance.
|Path to Drush||In this text box, specify the path to the Drush executable file. PhpStorm 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 PhpStorm loads command definitions automatically and returns to the Command Line Tool Support page.|
