Scare of My Life With GIT: I've got no branch!

I had checked out an old hash (commit) and was working on it, checking 开发者_如何转开发in merrily and ignoring warnings that I wasn't working in a branch. Then I switched to a branch and realized that I had no way to get back to my orphaned checkins (luckily I had the terminal window open still, so I checked it out and branched).

How can I get GIT to tell me the names of the commits that do NOT belong to a branch? Or just all the commits, if that's not possible...

git reflog will show the log of the references created by recent activity you've done. For future reference, git checkout of a commit puts you on an detached head. If you want to base work on an old commit, you should create a branch off of that commit instead.

git checkout -b newbranch oldsha1

or

git branch newbranch oldsha1
git checkout newbranch

See this question which has a great explanation of how to find stashes you've dropped. You can see dangling commits etc. the same way.

You can fish them out of the reflog, which stores the commits which you've had checked out.

git reflog will print out the most recent commits pointed to by HEAD, which is your working copy.

You can also get a list of all objects in your tree which are unreachable from your current branches using git fsck.
