This is expected behavior because have not used git add to promote these changes to the Staging Index. Then, the Staging Index and Working Directory are reset to match that of the specified commit.

The Staging Index and the Working Directory are left untouched. Reset is a command with many functional purposes, including giving users the ability to remove previously committed snap shots from the record entirely and—more commonly—to undo changes in the staging area and, primarily, the working directory. With this in mind lets execute a soft reset back to our first commit. Instead of operating on entire snapshots, this forces them to limit their operations to a single file.

Git reset single file in feature branch to be the same as in master

Git is a version control system that continues to grow in popularity with developers all over the world due its speed and excellent features. Originally designed for Linux kernel development, there are now versions of Git available for all the major operating systems, and more than one-third of all professional software developers reportedly use it as their primary source control system. The number has continued to grow over the years as businesses are looking more and more for. Perhaps the most important feature of any version control system, Git included, is the ability for users to revert a file back to its previous version at any point. There are many different circumstances when you might need to make changes to a file in Git, however, and each of them requires a different command in the program to achieve the desired result. Git Checkout Before you undo any changes that might have been made, you may want to first view what has been changed historically first. The Git Checkout command is an ideal way to do this. Checking out a file allows you to view an old version of any individual file, and does not disturb the rest of the directory in the process. This way, you can see all the older states of a project without having to worry about altering the current state. What git reset a single file does instead is create a new snap shot appended to the one that you wanted to undo with all the previously changed components returned to their prior state. In doing so, even when you revert files back to previous versions, you still have a complete revision history to reference at any point you need to access it. This can prove useful when it comes to working together in big teams with everyone assigned to different tasks. Communication is far simpler when everyone remains on the same page regarding any git reset a single file all changes to the project as a whole. When using Git, that process is not reverting, but rather resetting, which is discussed below. The main reasons a user would choose the revert command over reset is that it will not alter the project history and that it also allows users to target a specific individual commit at any point the project and remove only it. This is much faster than undoing all of the commits that occurred after the one you are targeting and then re-adding those deleted ones back afterwards. Git Reset Git Reset is similar to the Git Revert command, only considered a little more dangerous. Unlike Revert, the Reset command undoes whatever changes you just made to a file but does not store a snap shot of the alterations before getting rid of it; think of it more like an undo that cannot be undone. Reset is a command with many functional purposes, including giving users the ability to remove previously committed snap shots from the record entirely and—more commonly—to undo changes in the staging area and, primarily, the working directory. Reset is intended for use only on a local level, however; once snap shots have been shared with other developers other than yourself, removing it from the record is not good practice when collaborating with an entire team. Git Clean Lastly, there is the Git Clean command, which completely rids your project of any files that are not being tracked. Users can also find untracked files with the Git Status command and manually remove the ones that show up as being under that status, but Clean is a much simpler, faster method for doing so. Be forewarned, however, that much like the Reset command, there is no way to undo it once these untracked files are removed from a project. You will want to make sure that you have no desire to revisit the untracked files at any point before you run the Clean command.

Because of their distinct goals, the two commands are implemented differently: resetting completely removes a changeset, whereas reverting maintains the original changeset and uses a new commit to apply the undo. It is necessary to do git rm first because git checkout won't remove files that have been added since. The , , and commands are some of the most useful tools in your Git toolbox.

Some coding sessions go sideways, fast. But then I cannot push any changes because it is behind the remote.
