After a break from using AWS I had reason to reacquaint myself with it again today, and did so via the CLI. The AWS CLI is pretty intuitive and has a good helptext system, but one thing that kept frustrasting me was that after closing the help text, the screen cleared—so I couldn't copy the syntax out to use in my command!

The same thing happened when I ran a command that returned output - the screen cleared.

The fix: make sure that `AWS_PAGER` is set to the correct invocation of `less`. Or other options, including setting `--no-cli-pager` argument. This https://docs.aws.amazon.com/cli/latest/userguide/cli-usage-pagination.html#cli-usage-pagination-clientside[is documented] if you want to read more.
