$ git add git_GitHub.md
error: bad signature
fatal: index file corrupt

Cause Analysis

Because index file generally refers to the file .git/index in git. This file saves the information in the temporary storage area (index information). You can use git ls-files –stage to view the contents of the staging area. This file is very important! But now it reports index file corrupt, indicating that this file has been damaged. Fortunately, we have a way to regenerate this file: git read-tree or directly git reset.

Solution

  1. Enter the project directory: cd /path/to/dir
  2. Delete or rename the .git/index file: rm -f .git/index or mv .git/index{,.bak}
  3. Rebuild .git/index: git read-tree or directly git reset

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

$ git reset
Unstaged changes after reset:
M       Git/git_use.md
M       Git/git_para.md
