For example, I have the following across multiple files (over 200+ files) --- title: 'abcdefg' tags: - new - stuff --- And I needed to replace title: 'abcdefgh' with title: "abcdefgh". To do that, I’m going to use sed because its going to be terribly painful to do this manually. https://dchua.com/posts/2015-10-24-timestamp-your-bash-output/ Sat, 24 Oct 2015 00:00:00 +0000 https://dchua.com/posts/2015-10-24-timestamp-your-bash-output/ If you need to find out the time difference between bash outputs, you can use ts from the moreutils package.
