Can I delete a dangling branch in my Git history if the merge is empty?

Question

I am new to Git and have the newb following dilemma. I moved my old svn repo to github initially by just initializing a repository full of the files from my svn repository (minus the .svn stuff). Then, later I read that I could import my svn history, maintaining the history. So I deleted all contents of my master branch on github and then merged it in with my imported svn master. Then I pushed this up to github, so my commit history is something like

svn1 <- svn2 <- ... <- svnX <- E <- o <- o <- ... <- HEAD
                              /                        
                   A <- B <- C

where A is the initial commit (just copied files from svn repo), C is the where I deleted all of the stuff uploaded in A, and E is the merged of git-svn stuff and the initial repo.

So my question is, can I get rid of A through C in the history since I merged an empty directory at E? I've been reading about git rebase, and tried several things, but nothing worked.

Thanks! Ian

Problem is phylosophy. Don't create problems for yourself that you subsequently resolve. You can always start from scratch and recreate your repo on Github.

Answer 2

Are A, B, and C already in your master branch? If so, you can just go ahead and delete the branch with git branch -d <branch>. If that gives you errors, you can override it by using a capital -D.
