+
+Try this:
+
+branch_to_ignore='git-annex|master|newroot'
+for branch in $(git for-each-ref --sort=-committerdate refs/heads --format='%(refname:short)' | egrep -v $branch_to_ignore )
+    do git rebase --onto master \"$branch~\" \"$branch\"
+    echo \"Rebasing branch $branch onto master....\" 
+done
