Discussion on: What are your UNIX pipeline commands that saved you from lot of coding/time?

I use this pattern to find out the last commit that for which a certain condition was true, e.g. in which something wasn't yet broken.

In this example, test.sh just returns a non-zero code to mimic the condition you want to check for, but this could be anything that can be tested in a shell conditional.

until ./test.sh; do git checkout HEAD~1; done;
