Obtain list of actively used locales - Magento 2 CLI

Question

I know that with bin/magento setup:static-content:deploy en_US en_GB I can generate the static content for the above two locales.

How can I look up which locales are actively being used by a store (Imagine someone gave you ssh logins to a store you don't know which locales are used)?

So effectively I am looking for command XXX which should produce en_US en_GB (ideally something that is supported on 2.1)

Answer 1

Provided the locales have been previously deployed this works:
ls pub/static/adminhtml/Magento/backend/
but is not guaranteed to be there/complete and does not account for the frontend potentially having themes and different locales for each.

EDIT: slightly better option:

user@host:/var/www$ find pub/static -maxdepth 4 -mindepth 4 -type d
pub/static/frontend/Magento/luma/ca_ES
pub/static/frontend/Magento/luma/en_US
pub/static/frontend/Magento/blank/ca_ES
pub/static/adminhtml/Magento/backend/de_DE
pub/static/adminhtml/Magento/backend/ca_ES
pub/static/adminhtml/Magento/backend/en_US

Answer 2

from your root folder, run this command:

php ./bin/magento config:show general/locale/code

that should show you what locale has been configured across your websites/ store view

Answer 3

You can do this reliably in Magento 2.1 onwards with GetPageSpeed n98-magerun2 commands, e.g.:

n98-magerun2 deploy:locale:active
#> en_US en_GB
