$ git add git連接GitHub以及推送至倉庫.md
error: bad signature
fatal: index file corrupt

原因分析

由於index file在 git 里面一般指的是 .git/index 這個文件。這個文件保存的是暫存區的信息（索引信息）。可以通過 git ls-files --stage 來查看暫存區的內容。這個文件很重要！但是現在報 index file corrupt，說明這個文件已經損壞了。還好，我們有辦法重新來生成這個文件：git read-tree 或者直接 git reset.

解決辦法

1. 進入到工程目錄下: cd /path/to/dir
2. 刪除或重命名 .git/index 文件： rm -f .git/index 或 mv .git/index{,.bak}
3. 重建 .git/index : git read-tree 或者直接 git reset

$ mv .git/index .git/index.bak

$ git reset
Unstaged changes after reset:
