I happen to have this exact need come up recently. I have a few Bash scripts that I run once in a while. They evolve each time I run them, because often I will discover some missing things, or improve them a bit as I use them. They also fail a lot, due to the experimental nature. Now the problem is that every time they fail, I need to restart it. But not from the beginning, but where it failed. So I comment out everything before the failure and rerun. It would be nice to use durable execution for this.
