Magento 2 bin folder missing can't run any cli commands

Question

I am working on a client's shop, and the bin folder is missing, how can that be possible? Can I recreate it with the files inside? Its a noob question but I never faced this issue...

Answer 1

it looks like a Magento 1

are you sure it's Magento 2 and you in the right folder?

you can use something like: MagentoVersion.com to check your website version

for Magento 1 you can use n98-magerun for cli
