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 {{[-a|--all]}}

• Restore any files deleted or changed since the last commit:

git checkout-index {{[-a|--all]}} {{[-f|--force]}}

• Restore any files changed since the last commit, ignoring any files that were deleted:

git checkout-index {{[-a|--all]}} {{[-f|--force]}} {{[-n|--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 {{[-a|--all]}} {{[-f|--force]}} --prefix {{path/to/export_directory/}}
