CiviCRM Community Forums (archive)

I am trying to upgrade via Drush using the following commands, from version 4.2.0 to 4.2.6:

cd /home/dev9/public_html/
drush civicrm-upgrade -tarfile=/home/dev9/tmp_dist/newfiles/civicrm.tar.gz


But I get the following output:

I do not understand why drush is able to find the command "civicrm-upgrade" to get started, but then it loses it later.
