How to Automate pressing [ENTER] to continue in bash script

Question

I have a bash script that helps install a few applications automatically.

One app requests that I press ENTER to continue, or CTRL+C to cancel.

How can I automate my script to press ENTER when that prompt comes up?

`echo -e '\n' | your_command_or_script` should do the trick. — Robert Seaman, Jun 04 '20 at 15:42
@RobertSeaman `echo -e '\n'` is pointless and non-POSIX. Use `{ echo;echo; } | command` alone. — Léa Gris, Jun 04 '20 at 15:48

For simple enter or confirmation, consider using the yes command:

yes '' | command_or_script

For automating more complex interactions, consider using expect.
