I have seen this a few times in lectures. The KMS Grants lecture has crazy long commands that are difficult to follow. I would suggest that when the cli is used in labs that the line continuation option be used. Just add a "" before every option "–" and start a new line. This also makes the lab more readable. One simple example is:
This: aws kms encrypt –plaintext "hello" –key-id
aws kms encrypt
When the long key-id and grant-tokens text are added to this statement it’s MUCH easier to read.
Thanks for your suggestion!
