What's Wrong?

Bash command

   gh pr diff 17335 2>/dev/null | awk '/@@ -317,11 \+318,15 @@/,/^@@/' | head -25
   Check the org creation trial start route change

 Do you want to proceed?
 ❯ 1. Yes
   2. Yes, allow reading from ,/ from this project
   3. No

What Should Happen?

It should realize that that is not a path, and not ask for permission.
