Drush

Drush is a command line shell and scripting interface for Drupal, a veritable Swiss Army knife designed to make life easier for those of us who spend some of our working hours hacking away at the command prompt.

Site aliases

Drush uses site alias files to store context data. (Aegir still uses Drush 4)

drush help site-alias

example.aliases.drushrc.php

Copy to ~/.drush, rename aliases.drushrc.php or further.

Drush aliases
gist: drush aliases template

drush ev 'print_r(array_keys(drush_sitealias_get_record("@server_master")))'
drush ev '$a = drush_sitealias_get_record("@gk.dev"); print_r($a["path-aliases"]);'

Deployment

To sort with Aegir#Remote

drupal.org: Using drush to synchronize and deploy sites

drush help rsync
drush help sql-sync

Make

Drush Make is part of Drush as of Jan 2012.

.make files specify a recipe for modules, themes and libraries to be downloaded by Drush. Make files are used along with an install profile to make a distribution.

  generate make from a platform/site

Examples

example.make

http://drushmake.me/ - automatic generation demo

introduce an options array in the root level of the makefile

projects[drupal][version]  = "7.16"
projects[drupal][patch][]  = "http://drupal.org/files/1356276-base-profile-d7-39-do-not-test.patch"

projects[sasson][type] = theme
projects[sasson][version] = 3.x-dev
projects[sasson][download][type] = git
projects[sasson][download][url] = http://git.drupal.org/project/sasson.git

local files;

Libraries

.make files can specify external libraries to be downloaded using the Libraries API module.

; CKEditor
libraries[ckeditor][download][type]= "get"
libraries[ckeditor][download][url] =  "[ckeditor zip url goes here]"
libraries[ckeditor][directory_name] = "ckeditor"
libraries[ckeditor][destination] = "libraries"
