How to get the commit hash ID for a file?

I used git checkout commit_hash path/to/file to rollback a file to an older version.

After that, I forgot the commit hash ID that I used to retrieve this file. I used git status path/to/file, it shows this file is modified even though I did nothing to this file (I think it compares to HEAD).

Is there any way to get commit hash ID of this retrieved file?

Try the command history | grep path/to/file.

Since there might be many commits that hold the same version of path/to/file, the result would not be precise enough through git commands. Here's one of the tries.

git hash-object path/to/file

And you'll get a hash number($hash). It's the blob name of the very version of path/to/file.

for commit in $(git rev-list --all --reflog);do
    git ls-tree -r $commit -- path/to/file | if grep $hash;then echo $commit;fi
done

All the candidates will be printed and you'll have to identify the commit in your memory among them all. Maybe then git log -1 $commit would make it more recognisable than then echo $commit.

You could use 

git log filename

It would show the file log starting from the latest. If you forget, you could use shell history command. Assuming it's not too old.
