🚀 Reset in Git: How to Undo Changes

In Git, reset is used to undo changes at different levels—unstaging files, removing commits, or resetting your working directory.

📌 Types of git reset and Their Uses

1️⃣ Soft Reset (--soft)

✅ Keeps your changes & moves HEAD to a previous commit
✅ Use when you want to change commit history but keep changes

git reset --soft HEAD~1

➡ Moves HEAD back one commit but keeps your changes staged.
➡ Now, you can edit and recommit:

git commit -m "Updated commit message"

2️⃣ Mixed Reset (Default)

✅ Unstages changes but keeps the files
✅ Use when you want to undo a commit but keep the changes

git reset HEAD~1

➡ Moves HEAD back one commit
➡ Your changes remain unstaged, so you can add them again with:

git add .git commit -m "New commit message"

3️⃣ Hard Reset (--hard)

🚨 WARNING: This permanently deletes commits and changes!
✅ Use when you want to remove everything, including uncommitted changes

git reset --hard HEAD~1

➡ Moves HEAD back one commit
➡ Deletes all changes permanently

🔥 Reset to a Specific Commit

Instead of HEAD~1, you can reset to a specific commit:

git reset --hard <commit-hash>

Find commit hashes with:

git log --oneline
