# How to undo a git pull

Have you ever been working on a project, ran a `git pull` only to realise you've majorly messed up? Now all your code has been overwritten with whatever was in your remote repository - and sometimes this **isn't** what you want. In times like this, it's easy to panic, but fortunately there are a few ways to revert your code back to its old state and undo the `git pull`.

First things first, make a copy of your project in case you cause things to get worse. Also note that these commands will cause you to lose all uncomitted changes - so a backup can help you save that stuff before you continue. At least then, you'll have the version you currently have. After you've done this backup, you'll want to get a list of all your commit history. You can do this by running `git reflog`:
```shell
git reflog
```

This will generate a list that looks like this:
```shell                                       
648e314 (HEAD -> master, origin/master) HEAD@{0}: commit: Design refresh
b0168ee HEAD@{1}: commit: Minor CSS tweaks
514a02f HEAD@{2}: commit: Fixed extra curly brace
b432ba7 HEAD@{3}: commit: fixed border-radius
a707d13 HEAD@{4}: commit: fixed image border-radius
abf89a3 HEAD@{5}: commit: updated look and feel
```

Select the version you want to revert to. For example, if I wanted to revert to 'Minor CSS tweaks', I'd select the ID `b0168ee`. Next, run the following command to revert your repository to that verson:
```shell
git reset --hard b0168ee
```

This is quite easy, and gives you a lot of control over which version you recover. However, another easier way to do this is to give a time. If you don't want to run `git reflog`, you can run the following command to revert to the version of your repository as it was 30 mins ago, assuming your branch is `master`. **Note**, if you have been working on a specific branch for a long time, this may revert you back quite far. In that case, you might be better using the previous method - but you should be fine if you have a backup. 😄
```shell
git reset --hard master@{"30 minutes ago"}
```
