 How to get lost files back resulting from running git add and git restore -s@ -SW?

Problem: 

suppose you ran

$ git add .

then you ran

$ git status

and saw that you have added some files which you did not want to add. 

(You did not run 

$ git commit

)

then you wanted to remove them from the index.

In haste, you ran 

$ git restore -s@ -SW

resulting in those files are gone away from your working tree (resulted from -W).

You want to get them back.

Solution:

Run

$ git fsck --cach --no-reflogs --lost-found --unreachable head

You will get a list of SHA1, which point to your lost files.

Then run

$ git show SHA1 > name_of_lost_file

one by one, every lost file will now be in your current work directory!
