In this example, it is zero, which means that is where HEAD currently is. The section is just an index that specifies where HEAD was n moves ago. If we were to navigate to a different branch such as main, then the HEAD -> section would disappear from that specific entry. This just tells us that HEAD is currently pointing to the commit id in the entry. This means that if we were to remove the branch named branch-prefix/v2-1-4, it would no longer appear in the reflog entry here. It should be noted that the actual refs themselves are not always stored in the entry, but are instead inferred by Git from the commit id in the entry when dumping the reflog. If a ref currently exists in the repo that points to the commit id, such as the branch-prefix/v2-1-4 branch in this case, then those refs will be printed alongside the commit id in the reflog entry. The first part 956eb2f is the commit hash of the currently checked out commit when this entry was added to the reflog. Here is an example of what a reflog might look like:ĩ56eb2f (HEAD -> branch-prefix/v2-1-4, origin/branch-prefix/v2-1-4) commit: fix: post-rebase errors Reflog records contain data such as the SHA-1 hash that HEAD was pointing to when an operation was performed, and a description of the operation that was performed as well. These reflogs can prove very useful in assisting with data recovery against a Git repository if some code is lost in a destructive operation. Refs themselves are branch names, tags, and symbolic refs like HEAD, which is always pointing to the ref or commit id that’s currently checked out. These log entries contain a SHA-1 hash of the commit associated with it and any references, or refs for short. Whenever you add data to your local Git repository or perform destructive operations, Git keeps track of all these using reference logs, also known as reflogs. In this article, I will demonstrate how one can use the git-reflog tool to recover lost code and commits. Thankfully, Git has tools that can assist with the latter case at least. Sometimes data is lost because of hardware dying, but other times it’s done by mistake. All my repositories are private (company regulations) so I wasn't sure how to create a reproducible example.Losing data can be very frustrating. Sorry I didn't add a reproducible example. I know that I don't have hundreds of merge commits, so what am I missing here? ![]() ![]() Instead of having a file with hundreds of lines, I get 24. In both cases, I loose hundreds of commit messages. Git log -pretty=oneline -no-merges -decorate=short 0.0.0.0.0.1> file3.txt Git log -pretty=oneline -no-merges -decorate=short mit2> file2.txt Then I try to narrow it down, so only write the history between two commits or two tags.$ git log -pretty=oneline -no-merges -decorate=short > file1.txt see the full history, no merge commits (written to file).check out the respective branch (dev in my case). ![]() ![]()
