I do not like the one that does the whole tree that much. I would think "git-read-tree -m HEAD" would be simpler and more efficient if you are reverting the whole tree. On the other hand, I designed --index-info to be compatible with ls-tree output (it is not an accident, it was designed). In git ls-tree HEAD frotz | git update-index --index-info "frotz" part does not have to be the exact path but can be a directory name. It means "revert everything in this directory". This is quite heavy-handed and you would probably want to run update-index --refresh afterwards. - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
