How should git reset be used?

The git reset command is used to move the HEAD pointer to a specific commit and decide whether to keep the changes in the working directory.

The usage instructions are as follows:

  1. : Set the HEAD pointer to a specific commit while keeping the changes in the working directory and staging area.
  2. Set the HEAD pointer to point to a specific commit, reset the staging area, but preserve the changes in the working directory.
  3. Set the HEAD pointer to a specific commit, reset any changes in the staging area and working directory, and revert to the state of the specified commit.

These can be a commit hash, branch name, or a relative reference to HEAD (such as HEAD^ or HEAD~2).

It is important to note that using the git reset command will alter the commit history, so extra caution should be taken when making changes to public branches.
