This allows you to work a lot faster by doing complex tasks in really short commands. PowerShell on Windows If you are using PowerShell on Windows, you can also set up aliases and functions. In order to checkout a remote branch you have to first fetch the contents of the branch. It is important to realize that at this point nothing refers to commit f. I want to add changes in one file to two different commits git add will add the entire file to a commit. Excepted from this license are code snippets that are explicitely marked as citations from another source. Run: git checkout branchX file1 This will retrieve the version of file1 in branchX and overwrite file1 auto-merged by Git.
This makes the manual copying of files much more straightforward. Is your problem caused by a file that was not under version control before branching off live and git-added after modification to master later on? I made several commits on a single branch that should be on different branches Say you are on your master branch. Please note though, in case it wasn't clear, that this is messed up thing to do. Consider a situation where you want to change the third last commit you made. Let's see if we can restore our deleted branch.
I accidentally committed and pushed files containing sensitive data If you accidentally pushed files containing sensitive data passwords, keys, etc. Lines starting with ' ' will be ignored, and an empty message aborts the commit. Granted, this is good if you want to merge all changes in some files and it's ok that you must re-do all commits. If you already have a local branch with the changes you only need to do steps 2 and 5-7. You can use a similar command to checkout a file from a previous commit. New Branches Git checkout works hand-in-hand with. I like the 'git-interactive-merge' answer, above, but there's one easier.
Check out the man page for git-apply for more options. In this case it is often needed to quickly get just some lines of code from the file in trunk, ignoring a lot of other changes that are not supposed to go into the old version. When checking out paths from the index, this option lets you recreate the conflicted merge in the specified paths. However, if you remove everything, the rebase will be aborted. Thanks for your suggestion though.
You don't want to accidentally combine any commits that have already been pushed upstream because someone else may have already made commits that reference them. I don't think I've ever been so delighted by a fatal error message. Essentially, they are extremely detailed, scenario-specific standard operating procedures. Now you can apply the changes which you missed applying when you initially commited that commit. Please note though, in case it wasn't clear, that this is messed up thing to do.
To see which branches you or others on your team pushed, see the Branches list in your repository: Branching is an advanced technique. We could hunt down the last commit to each of these files and feed that information to git cherry-pick, but that still seems like more work than ought to be necessary. . The parent number is the 1-based index of the desired parent on this line, the first identifier is number 1, the second is number 2, and so on. Amending the pushed commit is not enough, since anyone could have pulled the original commit containing your sensitive data in the meantime. However, maybe as a personal reminder, it can be achieved like the following: git checkout Example: git checkout f08a63ff4fa7b8479f8c698e5998ee1afcac3a4e Gemfile. Afterwards you will be ready to prepare your new files, repopulating the working tree, by copying them from elsewhere, extracting a tarball, etc.
To find out what branches are available and what the current branch name is, execute git branch. Then you replace pick commands with any in the list above, and you can also remove commits by removing corresponding lines. Git Checkout a Remote Branch When collaborating with a team it is common to utilize remote repositories. However, it will irreversibly change your history, and mess up the history of anyone else who had already pulled from the repository. The most common case is to have only one remote named origin. Make sure the master branch is up to date and all your changes committed, then: pick a9c8a1d Some refactoring pick 01b2fd8 New awesome feature pick b729ad5 fixup pick e3851e8 another fix Rebase 8074d12.
So long as you haven't yet shared any of these commits with anybody else, you can easily move them on to a new branch, and then remove them from your current branch. Also assume you have other directories like dir-to-retain in the target that you don't want to change and retain history. Let's say that you just blindly committed changes with git commit -a and you're not sure what the actual content of the commit you just made was. Now you can apply the changes which you missed applying when you initially commited that commit. I accidentally committed and pushed a merge If you accidentally merged a feature branch to the main development branch before it was ready to be merged, you can still undo the merge. If you only need to merge a particular directory and leave everything else intact and yet preserve history, you could possibly try this. Confused by the debate over which approach is 'correct'? You're picking changes by file instead of by commit, and you'll lose any existing commit information author, message.
