Finally, we switch to the new branch where your changes await you. The second command resets the main branch to just before the last commit, but leaves the changes you just made in the new branch. The first command creates the new branch we want to work with. This mistake can be fixed in three commands: git branch new-branch git reset HEAD~ -hard git checkout new-branch What you really wanted to do was commit them to a new branch, or to that dev branch you have specifically for breaking changes.Īll is not lost. but to the master branch of your repo by mistake. Git mistake #2: You committed changes to (local) masterĪnother common goof: You’ve dutifully committed a bunch of changes. Then, when you reach a major milestone, use git merge -squash from your throwaway branch to save the results to the work-in-progress branch as a single, clean commit, and use the notes you’ve taken for the commit message. As you do this, document the major changes you’re making somewhere - don’t wait until you’re faced with the git commit command line to write it all down. If you’re working on something where you’re constantly making small commits to track incremental revisions, do them in a throwaway branch. One way to avoid this kind of mistake is to tweak the way you make commits in Git. If you are just changing files, and you don’t need to amend the commit message, you can use git commit -amend -no-edit to add the files and skip the message editing process. (This last step is the one that often flusters Git newcomers, who don’t always realize that the built-in Git editor is very much its own animal.) Once you’re done, hit Esc, then type :xq to save and exit from the editor. Then type git commit -amend to edit the commit message. First, if you have new changes to be staged, do that. Or you forgot to add certain details in the commit message. Let’s say you committed some work to a local branch, then realized you didn’t stage a number of needed files. ![]() This is one of the easiest Git blunders to recover from. Git mistake #1: You forgot to add changes to the last commit The further you go down the list, the bigger the disasters get. Here is a list of several of the bigger Git boo-boos, along with tips for backing out of them and preventing some of them. But with a little care - and provided you don’t panic - you can roll back from some of the worst Git disasters known to programmers. Some Git mistakes are more intimidating and difficult to reverse, even for experienced Git users. If you do something as simple as mistakenly delete a file, or you discover that the changes you’ve made to a dozen files were all ill-advised, you can undo what you’ve done with little hassle. By checking out a branch by name, you go to its latest version.A big reason developers use a source control system like Git is to avoid disasters. ‘master’ is the name of the default branch. You will see … Result: $ git checkout master 02 Returning to the latest version in the master branch Run: git checkout master Note that the content of the hello.html file is the default content. But you don’t need to worry about that right now. Older git versions will complain about not being on a local branch. The checkout command output totally clarifies the situation. If you want to create a new branch to retain commits you create, you mayĭo so (now or later) by using -b with the checkout command again. State without impacting any branches by performing another checkout. You can look around, make experimentalĬhanges and commit them, and you can discard any commits you make in this You will see … Result: $ git checkout 911e8c9 ![]() ![]() Since my hash values will be different from yours, substitute in the appropriate hash value for your repository everytime you see or in the command. Note: Many commands depend on the hash values in the repository. After that check the contents of the hello.html file. Use the code (its first 7 chars are enough) in the command below. You will find it in the last line of the git hist data. * 911e8c9 | First Commit Ĭheck the log data and find the hash for the first commit. * 8c32287 | Added standard HTML page tags * fa3c141 | Added HTML header (HEAD, master) gitconfig file? If you do not remember how, review the lesson on aliases. Note: Do not forget to define hist in your. 01 Getting hashes for the previous versions Run: git hist The checkout command can copy any snapshot from the repo to the working directory.
