GIT I want to cancel my checkout and get not committed changes back ! (Can I do that ?)

Question

I have done commit. Next I made some changes to a file. Then I run the command checkout for only one file. Which looks like this:

git checkout HEAD^ filename.php

That did not help me at all. So I would like to cancel my checkout. THE QUESTION IS: Can I go back to not only last committed but also to changes made after (not committed)?

Thanks for your help: :* Love You all :)

PS: I got the answer in comments bellow. To save you time guys. The answer was NO: :(

Answer 1

The modern command (since Git 2.23, Q3 2019) would be git restore :

git restore -- filename.php

It would restore the file content from, by default, HEAD.

But it would also overwrite the original content (local uncommitted changes), leaving you with alternatives like a VSCode timeline to get your local modification back.

A git restore -p or -m would at least attempt to merge hunks of code between the restore source and the restore location, instead of blindly overwriting everything.
