For complex project structure, may happen that multiple ‘.gitignore’ files or complex rules introduces unexpected ignore behaviour. Fortunately GIT provides methods to detect which rule affects file and can list all currently ignored files (or directories).

List all currently ignored files and folders

git status --ignored

Check which rule affects file

# Check single file
git check-ignore -v -- path/to/my/file

# or inspect all files in given directory
git check-ignore -v -- *
