# Git - misc
## Problem
My file lost!

Inside there is a zip file with the following contents
```
.git
HelloWorld.txt
```
Hello World is empty. `git log` shows that the repo only has the initial commit.
## Tools used
- `strings`
## Solution
Part of my initial checklist is running strings on everything, just to see interesting stuff. It's a mindless part of every challenge.
Run:
```bash
find . -type f -exec strings {} \; > ../result.txt
cat ../result.txt
```
Looking through it, this line caught my eye
```

```
Not really sure what each of the two commit hashes mean, but I assume one is the commit blob and the other one is the parent. Checking them both.
```bash
git checkout f4d0f6ddf6660f5c9273c84f3de64840a407bef1
ls
cat flag.txt
```
