Hi,

I have a standalone repository. File a.cpp has 3 versions. For example, I checked out version2(HEAD^).

> git checkout HEAD^ a.cpp

After a few days, I forget which version I have checked out. Is there a git command that can query which version is checked out? "git status" will show there is "changes to be committed", but with no the version information. Thank you!

Best regards, Halley

There may be an easier way to do this, but the way I do it is (sort of) documented in http://www.kernel.org/pub/software/scm/git/docs/user-manual.html#Finding-comments-With-given-Content (should be "commits" instead of "comments", but oh well!) and can be tweaked to suit yourself:

    git log --raw --abbrev=40 --pretty=oneline |
    grep -B 24 `git hash-object a.cpp`

There may be other, and possibly more efficient, ways to do this, but it generally works for me.

I do not see the reply to this thread. I'm unable to find how to find the version of a checked out file? Also, how do I view an older version?

Todd already answered to your address as well as to the list (3 days ago). Your 2nd question is answered in the same place he pointed you to:

http://www.kernel.org/pub/software/scm/git/docs/user-manual.html#viewing-old-file-versions

Now, what do you think is the top hit when googling "git view older version" ;)

No response probably because there is no notion of version of a file in Git.

Each commit is uniquely identified (SHA-1). A file is part of a commit.

I would recommend to read some Git tutorials, books that can be found on the Web. See Git wiki, or the online Pro Git book:
