2026/02/09 每日CTF
===
對不起拖了那麼久QAQ
最近沉迷minecraft太久了...


今日題目:Time Machine

### Hint1:The ```cat``` command will let you read a file, but that won't help you here!
### Hint2:Read the chapter on Git from the picoPrimer [here](https://primer.picoctf.org/#_git_version_control).
### Hint3:When committing a file with git, a message can (and should) be included.

今天這題看起來跟git有關係，看起來是要找commit時的紀錄
那就先把檔案下載下來，解壓縮後可以得到一個文字檔
內容如下:
```
This is what I was working on, but I'd need to look at my commit history to know why...
```
所以就cd進資料夾然後```git init```

那接著就是找紀錄，這邊我使用```git log```

那他只有一個歷史紀錄，而且flag就擺在這了
