$ pre-commit run cr-manager --all-files
# or particular file
$ pre-commit run cr-manager --files path/to/file$ git commit -m "your commit message"$ cr-manager [--update] --filetype python /path/to/file.txt# single file
$ cr-manager /path/to/file
# files recursively in directories
$ cr-manager --recursive /path/to/directory
# add to non-supported suffixes with supplied filetype
# -- e.e. add to .txt files as python files --
$ cr-manager --filetype python /path/to/file.txtTip
--filetype <TYPE> can be used to force a specific filetype for the update action, overriding auto-detection.
