The command "git revert HEAD~${4}" in Git is used to undo the changes made by the last 4 commits and creates a new commit to reverse those changes.

Here's a breakdown of the command:

• "git revert" is the Git command used to create a new commit that undoes previous changes.
• "HEAD" refers to the current commit in the branch you are currently on.
• "~" is a tilde symbol used in Git to specify the number of commits to go back in history.
• "${4}" is a placeholder indicating that you need to replace it with a specific number, in this case, 4.

So, "HEAD~${4}" means going back 4 commits from the current HEAD (or the latest commit on the branch).

When you run this command, Git will analyze the changes made in the last 4 commits and create a new commit that undoes those changes. This is useful if you want to revert or undo the changes introduced by those specific commits while preserving the commit history.
