Restore Deleted Files using Git

Sometime you can delete a file  ,by accident, and then you commit your changes . after a while you recognize that you need this file So what you can do ??

what I have tried to resolve such problem (there are several ways) is  this few steps :

1. List all files that have been deleted from my git repository :
   

   git log --diff-filter=D --summary
   
   

2. Search the commit where you deleted your file
3. undo your commit to the searched one BUT don't lose your modifications by taping this cmd :
   

   git reset --soft HEAD~n   
   

   
   n: is the number of undo commit steps


4. if you type  git status  you will re-view your deleted file so to get the file back type this cmd :
   

   git checkout -- [file name]
   

Hope this could helps someone :D
