You can use `git merge --squash` for this, which is slightly more elegant than `git rebase -i`. Suppose you're on master and you want to squash the last 12 commits into one. First check that `git status` is clean (since `git reset --hard` will throw away staged and unstaged changes) and then: # Reset the current branch to the commit just before the last 12: git reset --hard HEAD~12 # HEAD@{1} is where the branch was just before the previous command. # This command sets the state of the index to be as it would just # after a merge from that commit: git merge --squash HEAD@{1} # Commit those squashed changes. The commit message will be helpfully # prepopulated with the commit messages of all the squashed commits: git commit The [documentation for `git merge`](http://www.kernel.org/pub/software/scm/git/docs/git-merge.html) describes the `--squash` option in more detail. ---------- *Update:* the only real advantage of this method over the simpler `git reset --soft HEAD~12 && git commit` suggested by Chris Johnsen in [his answer](http://stackoverflow.com/questions/5189560/how-can-i-squash-my-last-x-commits-together-using-git/5201642#5201642) is that you get the commit message prepopulated with every commit message that you're squashing.
