Answer 1

For those who don't want to elevate the entire script (to limit risks by only using sudo within the script where needed) the first part of the accepted answer sudo echo "Thanks" works but won't respond to sudo password failure by exiting the script. To accomplish this, scripts that include sudo commands and want to ensure sudo access before it's used could start with

if [[ ! $(sudo echo 0) ]]; then exit; fi

The caveat is that you are relying on the existence of a sudoers timeout that will last the duration of your script to suppress the rest of the prompts.
