Traveling multiverse of git history

undo git commit

Have you ever made mistake and lost track of your code while working? but even after a bit of google research left confused about what to use between git reset, git revert, or the git checkout.

okay my friend I got your back. let's get into it.

Overview:

git checkout : go to previous commit

git log : fetching history

git revert : undo public changes

git reset : undo local changes

git clean : delete untracked files

Git checkout :

git checkout is a time traveler for your code. you can go back to a certain commit by using that commit hash and check what the code looked like at that time.

you can also travel to different branches using git checkout. It will let you travel the multiverse of git history.

git checkout hash

git checkout branchname

If you have uncommitted changes you can undo them by :

git checkout — — filename

for changes in more than one file, you can run

git checkout — — .

Git log :

Now, you must be wondering how can you find the associated hash with a specific commit. here git log comes into the picture .git log is used for fetching the latest commit info.

Just run the git log in your terminal.

Only need ID and associated commit messages? Use –oneline flag.

git log — oneline

Git Revert :

If you have committed changes you won't be able to use git checkout to undo them .instead you can use git revert.

reverting a commit

suppose you want to go back to the previous commit or want to undo a certain commit, you can use :

git revert commit_hash

git revert will be saved in the git history.

Git Reset

If you don't want the changes as well as the history of the code changes. you can use git reset. It is not recommended to use git reset in public repo cause those repos are used by other developers also. resetting commits can rewrite git history which can cause merge conflicts.

Use git reset when you are in your local repo.

git reset — — hard Head~1

this will reset behind one commit.

git clean

You can delete untracked files by using git clean.

git clean -f
