To revert to a previous commit in Git 1. Soft Reset (keep staged changes) git reset —soft commit-hash 2. Mixed reset(keep changes in working directory) git reset —mixed commit-hash 3. Hard reset(discard all changes) git reset —hard commit-hash 4.Revert(preserve history, recommended for shared branches) git revert comit-hash

To revert to a previous commit in Git, use the command `git revert <commit-hash>`, where `<commit-hash>` is the identifier of the commit you want to revert. This creates a new commit that undoes changes from the specified commit. If you want to move the branch pointer to an older commit instead, use `git reset --hard <commit-hash>`, but beware that this discards newer changes. Always ensure backups and understand the impact on shared branches.

I would keep it simple with examples, as steps are already added: 1. Revert the last commit 🔹 Command: `git revert HEAD` 🔹 Example: Undo changes made by the most recent commit while creating a new commit to preserve history 2. Revert a specific commit 🔹 Command: `git revert <commit-hash>` 🔹 Example: `git revert a1b2c3d` reverses changes from the commit with hash `a1b2c3d` and creates a new commit 3. Revert multiple commits 🔹 Command: `git revert HEAD~3..HEAD` 🔹 Example: Undo the last 3 commits, preserving history with new commits for each reverted one Decide based on which scenario fits your use case!😊

You can revert to a previous commit in Git using: git reset --hard <commit-hash> (Resets to a previous commit, erasing changes) git reset --soft <commit-hash> (Keeps changes staged) git revert <commit-hash> (Creates a new commit that undoes the changes) Use git log to find the commit hash.

To find a commit hash in Git, use git log in various ways: View commit history: git log – Shows detailed commit info. Concise history: git log --oneline – Displays short commit summaries. Limit displayed commits: git log -n 5 – Shows the last 5 commits. Search by message/author: git log --grep="bug fix" git log --author="John Doe" Shorthand references: HEAD → Latest commit HEAD~1 → Previous commit HEAD^ → Parent commit HEAD^^ → Grandparent commit

Using git checkout (for a detached HEAD state): This is useful if you just want to view or workgit checkout <commit-hash> Using git revert (to create a new commit that undoes changes): If you want to undo the changes made by a previous commit but keep the commit history intact, you can use git revert.git revert <commit-hash> This will create a new commit that reverses the changes from the specified commit. Using git reset (to reset the branch to a previous commit): If you want to move the branch back to a previous commitment you can use git reset. Be cautious with this, as it can change commit history.For a soft reset (preserves changes in your working directory) git reset --soft <commit-hash> For a hard reset git reset --hard <commit-hash>

$ cd /tmp/example $ git init Initialized empty Git repository in /tmp/example/.git/ $ echo "Initial text" > README.md $ git add README.md $ git commit -m "initial commit" [master (root-commit) 3f7522e] initial commit 1 file changed, 1 insertion(+) create mode 100644 README.md $ echo "bad update" > README.md $ git commit -am "bad update" [master a1b9870] bad update 1 file changed, 1 insertion(+), 1 deletion(-) In this example the commit history has two commits and the last one is a mistake. Using git revert: $ git revert HEAD [master 1db4eeb] Revert "bad update" 1 file changed, 1 insertion(+), 1 deletion(-) There will be 3 commits in the log: $ git log --oneline 1db4eeb Revert "bad update" a1b9870 bad update 3f7522e initial commit

Reverting to a previous commit in Git depends on whether you want to preserve history or completely erase changes. If you need to undo a commit but keep a record of it, you can use git revert <commit-hash>, which creates a new commit that cancels out the changes from the specified commit. However, if you want to fully go back to a previous commit and remove all changes after it, you can use git reset --hard <commit-hash>, but this is irreversible unless you have backups. A safer approach is git reset --soft <commit-hash>, which moves the branch back while keeping changes staged, allowing you to review and modify them before committing again.

The git revert command safely undoes changes by creating a new commit that negates a previous one, preserving history. Basic Usage 🔹 Revert the last commit: git revert HEAD 🔹 Revert a specific commit: git revert <commit-hash> 🔹 Revert the commit before the last: git revert HEAD~1 🔹 Revert multiple commits: git revert HEAD~3..HEAD Additional Options 🔹 Skip commit message prompt: git revert -n HEAD (modifies but doesn’t commit) ✅ Ideal for public repos ✅ Keeps history intact ✅ Safer than git reset --hard

Using `git reset` with example: (warning: it can be destructive if misused) 1. Soft Reset 🔹 Command: `git reset --soft <commit-hash>` 🔹 Example: Resets to a previous commit but keeps changes staged for editing or committing again 2. Mixed Reset 🔹 Command: `git reset --mixed <commit-hash>` 🔹 Example: Moves branch pointer to a previous commit and unstages changes for review 3. Hard Reset 🔹 Command: `git reset --hard <commit-hash>` 🔹 Example: Completely erases changes after the specified commit

As the tip mentions, git reset is destructive. So if you have pushed the branch and the commits to a remote, be cognizant that you'll have to force push (git push --force) to update the remote branch. This can affect other contributors or team members who have already pulled the branch. For this reason, some teams avoid destructive git operations in remote branches. If that is your situation, one suitable alternative to resetting is to create a new branch from the commit you want (HEAD~2 in this case) and then push the new branch up to remote.

The git reset command reverts to a previous commit but can be destructive if misused. 1. Reset to a Previous Commit 🔹 Hard reset (erases changes): git reset --hard <commit-hash> git reset --hard HEAD~2 (resets to two commits before the latest) 2. Types of git reset Soft reset: git reset --soft <commit> → Moves pointer, keeps changes staged. Mixed reset: git reset --mixed <commit> → Moves pointer, unstages changes. Hard reset: git reset --hard <commit> → Moves pointer, deletes changes. 3. Recovering from Accidental Reset 🔹 git reflog → View history. 🔹 git reset --hard <previous-hash> → Restore state. ✅ Use reset for local work, revert for shared repos.

It lets you temporarily switch to a previous commit without changing branch history. 1. Checkout a Previous Commit 🔹 git checkout <hash> – Moves to an older commit. 🔹 git checkout HEAD~3 – Switches to the state three commits before the latest. ⚠️ This puts you in a "detached HEAD" state (not on any branch). 2. Returning to Your Branch 🔹 git checkout main (or your branch name) 3. Modifying an Old Commit Since a detached HEAD prevents committing, create a branch: 🔹 git checkout -b new-branch <commit-hash> 4. Alternative: git switch 🔹 git switch --detach <commit-hash> – Switch without checkout. 🔹 git switch -c new-branch <commit-hash> – Create a branch from an old commit. ✅ Use checkout to explore old commits without affecting history.

Using `git checkout` with example use cases: 1. Switch to a Previous Commit 🔹 Command: `git checkout <commit-hash>` 🔹 Example: Temporarily view or test the state of an older commit without affecting branch history 2. Create a Branch from an Old Commit 🔹 Command: `git checkout -b new-branch <commit-hash>` 🔹 Example: Creates a new branch to edit or expand upon an old commit

I think that, more important than commands to revert/reset, is always paying attention to the operation and rechecking your code before committing. Doing your own code review truly minimizes the chances of needing a rollback

1. Undoing a Revert 🔹 If you mistakenly used git revert, you can revert it: git revert <revert-commit-hash> 2. Recovering Lost Commits After git reset --hard 🔹 Use git reflog to find lost commits. 🔹 Restore a lost commit: git reset --hard <lost-commit-hash> 3. Safeguarding Work Before Resetting 🔹 Save uncommitted changes: git stash 🔹 Restore later: git stash pop 4. Using git cherry-pick for Selective Changes 🔹 Apply a specific commit without resetting everything: git cherry-pick <commit-hash> 5. Best Practices for Safe Reversion ✅ Avoid git reset --hard on shared branches. ✅ Use git revert for safer undos. ✅ Always git pull before changes.

One effective way to avoid these issues is to adopt a workflow with separate branches for each feature or bug fix, ensuring that testing branches, such as dev, are preserved. In my daily work, I use a structure with main, dev, and secondary branches for features and fixes, minimizing destructive commands in the project’s history as much as possible. Additionally, it is essential to conduct tests and reviews before approving and merging pull requests, reducing risks and ensuring a more secure development process.
