git checkout-index

Copy files from the index to the working tree. More information: https://git-scm.com/docs/git-checkout-index.

• Restore any files deleted since the last commit:
  git checkout-index --all
• Restore any files deleted or changed since the last commit:
  git checkout-index --all --force
• Restore any files changed since the last commit, ignoring any files that were deleted:
  git checkout-index --all --force --no-create
• Export a copy of the entire tree at the last commit to the specified directory (the trailing slash is important):
  git checkout-index --all --force --prefix={{path/to/export_directory/}}
