Installation

1. Install a global version of Drush using Composer

   composer global require drush/drush:dev-master
   

2. Shared Hosting

   To make it easier to use, add an alias to your .bash_profile or .bashrc file:

   alias drush='~/.composer/vendor/bin/drush'
   

Drush Launcher

Drush Launcher is basically a small wrapper that is triggered when you run drush. It looks if you're inside a Drupal project directory, then finds if there's a local version of Drush installed with the project. If so, it uses that version of Drush, configured for each Drupal project you work on.

For convenience, instead of passing the --fallback option any time you're using Drush outside a Composer-based Drupal project directory, you can set the environment variable DRUSH_LAUNCHER_FALLBACK, for example in your .bash_profile:

export DRUSH_LAUNCHER_FALLBACK=~/.composer/vendor/bin/drush
