How to search a Git repository by commit message?

Question

I checked some source code into GIT with the commit message "Build 0051".

However, I can't seem to find that source code anymore - how do I extract this source from the GIT repository, using the command line?

The source code is definitely there, now its a matter of checking it out:

C:\Source>git log -g --grep="0052"

commit 77b1f718d19e5cf46e2fab8405a9a0859c9c2889

Reflog: [email protected]{10} (unknown <[email protected](none)>)

Reflog message: commit: 20110819 - 1724 - GL: Intermediate version. File version:  v0.5.0 build 0052.

Author: unknown <[email protected](none)>

If you have lost the history of the commit, look for the ‘build 0051’ in the commits listed by reflog using:

git reflog

Then you need to set your head to the commit where ‘build 0051’ is not visible.

Then to recover commits from reflog do:

git checkout <commit_id> 

# alternative, using reflog (see git-ready link provided)

# git checkout [email protected]{10} git checkout -b build_0051

# Make a new branch with the build_0051 as the tip

This will help you to push to github.
