Learn how to retrieve old versions of code.
- [Instructor] In this movie, we'll talk about how … to retrieve old versions of files. … In the previous movie, we saw that Git only allows amending … the most recent commit, … and that's important because Git is trying to maintain … data integrity along the chain of commits … and if it were easy for us to start editing the … history of commits, … then we wouldn't have that data integrity. … We wouldn't be able to trust that nothing had changed. … Instead, if we want to undo some changes that we've made, … the right way to do it in Git is to make those edits … into new commits, so it accurately reflects what happened. … Let's say we changed a word from singular to plural, … we make a commit. … Then, if we want to change it back from plural to singular, … then we should make another commit. … It may have been days or weeks since that change happened … or it may have happened recently, … but we want to reflect the fact that two different … commits were changed, … even if what's happened is that we've just changed our mind. …
