When you git revert a previous commit, the only things plucked out of your development environment are the changes explicitly associated with the reverted commit. A revert is an operation that takes a specified commit and creates a new commit which inverses the specified commit. The --no-commit flag lets git revert all the commits at once- otherwise you'll be prompted for a message for each commit in the range, littering your history with unnecessary new commits. But you should do it rather fast before anyone fetches the bad commits, or you won't be very popular with them for a while ; First two alternatives that will keep the history intact: Alternative: Correct the mistake in a new commit Simply remove or fix the bad file in a new commit and push it to the remote repository. Another way: Checkout the branch you want to revert, then reset your local working copy back to the commit that you want to be the latest one on the remote server everything after it will go bye-bye. Unreferenced commits remain in the repository until the garbage collection software is run by system. And if I pull from the remote it ends up back where it was at the latest commit on the remote branch.
This will have Git open the configured system editor and let you modify the last commit message. How to revert a git commit In the name of simplicity, this git revert example will start off with a completely clean repository. It brings together multiple lines of development. So now git status shows the changes you had checked into C. If your push is a few days old or not the immediate last one, this can become tricky because rewriting history affects every other people or cloned repo out there.

Then navigate to your repository's local directory and run this command: git -c diff. To help you decide, you want to take a look at the state of the project before you started your experiment. Firstly let's deal with unwanted file.
After garbage collection in your local repository, it will be like the unwanted commit never happened. So, if I add a new commit to my feature branch, and then try to merge that branch back into master, will I only get the new changes and not the changes I reverted? Also, as I checked the local repo folder, it shows all files tst1. That's why we provide our guides, videos, and cheat sheets about version control with Git and lots of other topics for free.
