could please anybody tell us if it is possible and if it is not, what is the best alternative to do it ? This is how it would be done in command line :
git checkout HEAD~1 -- path/to/file
But if the project is big, navigating to that file in cmd can be annoying ….
You can do this with EGit version 1.0 or higher (it might also be possible with earlier versions, but 1.0 is the first version I noticed the feature).
