git commit回滚

1，HEAD^   表示 最新提交HEAD位置往回数一个提交， 几个 ^  就往回数几个提交；

2，HEAD~n  表示 新提交HEAD位置往回数n个提交

1， `rebase -i`是 `rebase --interactive` 的缩写；
2,  `git rebase -i` 不仅可以删除commit， 还可以修改commit。 具体的可以查看rebase 中提示的参数

$ git rebase -i HEAD~2

drop e47fa58 提交11
pick 338955c 提交12

# Rebase 7f83da3..338955c onto 7f83da3 (2 commands)
#
# Commands:
# p, pick <commit> = use commit
# r, reword <commit> = use commit, but edit the commit message
# e, edit <commit> = use commit, but stop for amending
# s, squash <commit> = use commit, but meld into previous commit
# f, fixup <commit> = like "squash", but discard this commit's log message
# x, exec <command> = run command (the rest of the line) using shell
# b, break = stop here (continue rebase later with 'git rebase --continue')
# d, drop <commit> = remove commit
# l, label <label> = label current HEAD with a name
# t, reset <label> = reset HEAD to a label
# m, merge [-C <commit> | -c <commit>] <label> [# <oneline>]
# .       create a merge commit using the original merge commit's
# .       message (or the oneline, if no original merge commit was
# .       specified). Use -c <commit> to reword the commit message.
#
# These lines can be re-ordered; they are executed from top to bottom.
#
# If you remove a line here THAT COMMIT WILL BE LOST.
#
# However, if you remove everything, the rebase will be aborted.
#
# Note that empty commits are commented out
