Drush

If you have been read Some basic drush commands, you can use Drush by running drush cr command line. However, this way is not useful when you're in the development process because you need to run the command line every time you change the code.

I'll guide you follow 2 ways:

Following these below steps to install Drush 8 (Ubuntu and MacOS):

The current version of Drush 8 when I writing this article is 8.2.1

1. Choose the latest version of Drush 8 in the below link: 

https://github.com/drush-ops/drush/releases

You can choose v8.2.2 and download the drush.phar. You can use the bellow command line to download it:

wget https://github.com/drush-ops/drush/releases/download/8.2.1/drush.phar

Note: to use the wget command line, you need to install it first.

Drush is a supporting tool, which is important for any Drupal developers. It helps executing a task with many steps simpler through one command. It's also really helpful in deployment process through integrating it in script.

I will share some basic Drush commands that I usually use:

1. Clear cache / Cache rebuild.

For Drupal 7

drush cc all

For Drupal 8/9

drush cr

2. Delete all tables in the database (available on Drupal 7/8/9).
