Hi @amaoo - thanks for reaching out.

I'm not sure if I understand the statement "use ctrl+c to exit the command, which will result in the input not being displayed and the carriage return not being wrapped."

Can you please elaborate more on that? When I ran the command, it listed out all the certificates where you can extend the output by pressing arrow down, then I exited with ctrl+c and results are still displayed above.

Hope to hear back.

When (END) appears, typing ctrl +C exits the aws command. However, when you type Enter, there is no line feed. It is not displayed when you type any command.
The same problem occurs not only with the aws rds command, but also with other commands that output too long a line.
Only when stty sane is typed does it return to normal.

@amaoo thanks for providing additional details.

This's actually expected behavior when using the default pager less in CLI v2 in AWS CloudShell. It only happens when the output is long enough to require scrolling where CLI pipes the output to a pager program like less. This allows you to scroll through the output and examine it before returning to the command prompt.

The (END) indicates you've reached the end of the paged output. To exit the pager and return to the prompt, you can press q rather than Ctrl + c command.

There are a few ways you can disable this pager, see here.

Hope that helps,
John
