Using atom to script for aws

Question

So I using ATOM to create a script to use with AWS, and after I run it I got a lot of resources to delete, any chance I can run just part of the script, using all variables, instead of running all script again? So I don’t have to delete all resources each time part of my script not working.

post your code, if you want to clean up after the script exits check `help trap` — Diego Torres Milano, Nov 14 '20 at 05:43
