问题
The question is related to the question "How to restore Git after fatal file system error?", but for a single file.
I need to get to last state 2009-07-27 23:58, where I need the file:
/Users/henri/BAckup/6-relationdiagram/Normalized_perhaps_DB/simple_schema0.tcuml
How can I restore the file after a crash?
ADDED: Where will I find the file? What are they supposed to do?

回答1:
sometimes i delete a file or directory in my git local and i want to restore just that file. i run the following command:
git checkout -- filenameOrDirectory
note the spaces in between.

If you need to get a single file out of a commit that is in your repository then git checkout will do it for you. Specifically:
git checkout <sha> <filename>
will retrieve the file <filename> from the commit <sha> into your current working copy. can be any reference to any commit, so it could be a branch name, a tag name, HEAD^^^^, or anything at all like that that you want...

Do you have an uncorrupted copy of the repository anywhere? If so, pull from there to your working directory and then checkout the file. You can do:
git log --since='2009-07-27 23:58' --pretty=oneline -n 1
to get the hash you want and then get the file via:
git checkout <file> <hash>
If you have no uncorrupted working copies of the repository, you might try 'git fsck', but your chance of success is small or zero if files have been lost.
