Change drush language Suddenly my drush has switched language and displays error messages in my native language, which is unfortunately not convenient if one tries to search for solutions on these errors. 

Do you know how to switch the language of drush errors back to English?
Adding the following string to drushrc.php worked for me with Drush 5.4:

$options['variables']['language_default']-&gt;language = 'en';


In my setup I placed drushrc.php into sites/default/drushrc.php, for other possible locations see documentation in examples/example.drushrc.php in Drush installation directory.
