Git helps us in many ways when working with shared repositories.

We can perform many functions using Git as we can create a new branch, merge a branch, delete a branch as per our requirements. These operations can be done using multiple Git commands.

The command git resetis a composite and multi-source function used to undo changes. The command can be used with three main options: --soft, --mixed, --hard.

These three parameters correspond to Git's management mechanism, called the commit tree ( HEAD).

HEADIndicates the last commit when Git switched branches. In addition, we can also say Git HEADthat points to the last commit of the current branch.

When we switch branches or create a new branch, Git HEADwe transfer the latest commit to our local branch. More precisely, HEADa pointer that always points to the current commit, which may or may not belong to the current branch.

Git HEAD reset

When we have saved our changes to our desired repository, we should relax because we have already git resetreturned to our completed changes using the command, which will bring our current branch back to its original location before the command was run.

option HEADto publish a new branch. We can say that git reset-hard HEADwhat can be done is to clear out all the uncommitted changes we have made.

git resetCommands can be combined with other commands:

• Transfer to HEADthe content pointed by the branch.
• Make it look like a tree object.
• Looks like the current working folder.

Moreover, there are two different categories git reset.

Git Head Reset--soft

This Git command will reset HEAD. But our index and working directory will not be affected in any way.

We can use the Git reset command option to reset the head of our local branch:

git reset --soft

Git Head Reset--mixed

git resetThe mix command will change the head position to the specified commit and further remove the changes from the staging area. Here is an example of undoing the changes.

So if we run the Git reset HEAD command, it will HEADmove back to the first parent commit again. The syntax for the above case is as follows:

git reset --mixed or $ git reset

Git Head Reset--hard

This command can be a hindrance for us. We can use it only if we know exactly how to use it.

This was a problem for us when we used git reset-hard HEADrevert to the last commit. Luckily, we developers have a better solution to correct it.

Be aware that git reset --hardgit status is a threatening command. It can smash all our uncommitted changes. We should check it first and make sure the Git status output is clean before processing it.

If we want to remove all commits in both the index and the staging area (we need to undo our last commit and the last commit before that), this command will remove the commits stored in the index. We can use --hardthe Git reset command with the -r option:

git reset --hard HEAD~2

This command will remove any commits from the index and staging area. It will also remove the commits from the history.
