∞ install Drush from CVS HEAD on any unix server
## ## Installs Drush (the Drupal Shell command line utility) from CVS HEAD ## on any UNIX machine, such that all users that have /usr/local/bin in ## their $PATH can use Drush (granted they have access to a Drupal install). ## ## cd /usr/local/src cvs -z6 -d:pserver:anonymous:anonymous@cvs.drupal.org:/cvs/drupal-contrib checkout -d drush-HEAD contributions/modules/drush/ curl -O http://download.pear.php.net/package/Console_Table-1.1.3.tgz tar zxvf Console_Table-1.1.3.tgz cp Console_Table-1.1.3/Table.php drush-HEAD/includes/table.inc ln -s /usr/local/src/drush-HEAD/drush /usr/local/bin/drush ## ## now any user that has /usr/local/bin in their $PATH can use Drush. ## ## ## ... later on, to keep drush up to date, run the following: #cd /usr/local/src/drush-HEAD #cvs update -dPA
