It depends what you mean with "safe way".

git checkout, git checkout -f or other combinations will only

overwrite/rewrite the files in the working tree, if, and only if,

git comes to the conclusion that "git add" will do something,

like replace a blob for a file in the index.

(And by running "rm .git/index git will evaluate the "clean" filters,

and the CRLF->LF conversion).

If you want to test a smudge filter, simply remove the file:

mv file /tmp && git checkout file
