The first is to use drush.wrapper located within the /vendor/drush/drush/examples folder. This file is a wrapper script that launches Drush within a project. If we open the file within an editor, we will see that it states we need to copy the file to our /web folder and rename it to drush.
Choosing to follow this method would then allow us from within the /web folder to execute drush commands by entering the following within our Terminal window:
./drush
This is a little better; however, this is not quite as nice as simply typing the word drush without the need to know how to run a script. We can accomplish this by globally installing Drush using Composer.
