Drush is the best tool for Drupal development and administration. I liked it since the firt time I used it. I consider it an essential tool for Drupal.
Downloading and enabling a module is as simple as typing “drush en -y module_name”.
$ d en -y url url was not found. [warning] The following projects provide some or all of the extensions not found: [ok] url Would you like to download them? (y/n): y Project url (7.x-1.0) downloaded to sites/all/modules/contrib/url. [success] The following extensions will be enabled: url Do you really want to continue? (y/n): y url was enabled successfully.
This is a simple example of drush, however it can be extremely useful for task as migrations. Check it!
