If you have lost track of a recent commit (perhaps you did a reset), you
can generally still get it back. Run git reflog and look through the
output to see if you can find that commit. Note the sha value associated
with that commit. Let's say it is 39e85b2. You can peruse the
details of that commit with git show 39e85b2.
From there, the utility belt that is git is at your disposal. For
example, you can cherry-pick the commit or do a rebase.
