Drush mal eben auf einem Debian 7 mittels apt-get install drush installiert.
Irgendwann kommt es mal wieder zu einem Drupal Core Update und schnell wird auf drush zurückgriffen.

Was ist aber zu tun, wenn ein derartiger Fehler erscheint?
drush pm-update throws huge error stream like :strpos(): Empty delimiter pm.drush.inc:1131

Es ist drush zu updaten….

Code updates will be made to drupal core.
WARNING:  Updating core will discard any modifications made to Drupal core files, most noteworthy among these are .htaccess and robots.txt.  If you have made any modifications to these files, please back them up before updating so that you can re-create your modifications in the updated version of the file.
Note: Updating core can potentially break your site. It is NOT recommended to update production sites without prior testing.
