I am trying the new Einstein Intent API basics module. One of the units directs us to download cURL and then in 'Create the Dataset' we are to use the following command to load the .csv file:

curl -X POST -H "Authorization: Bearer <TOKEN>" -H "Cache-Control: no-cache" -H "Content-Type: multipart/form-data" -F "type=text-intent" -F "path=http://einstein.ai/text/case_routing_intent.csv" https://api.einstein.ai/v2/language/datasets/upload

This results in a message stating curl is not recognized as a command. If I change the " to ' as suggested in the unit, I get a message stating the file can't be found.

I did exactly what was told in the trail yet i am unable to find the custom link( not a member?) in the login page .....check the images and help me ..stuck here for last two days
