前言

之前在pr代码时, 被要求将某几个提交合并为一个提交后重新提交。
这里需要用的git rebase -i来完成。

‘git rebase -i’的简单使用

git rebase -i的作用很多, 可以在本文末尾点击官网链接查看, 我们这里只介绍涉及到前言需求的压缩提交这一个用途:
压缩提交
通过交互式变基工具，也可以将一连串提交压缩成一个单独的提交。在变基信息中脚本给出了有用的指令：

#
# 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

如果，指定 “squash” 而不是 “pick” 或 “edit”，Git 将应用两者的修改并合并提交信息在一起。所以，如果想要这三次提交变为一个提交，可以这样修改脚本：

1
2
3

pick f7f3f6d changed my name a bit
squash 310154e updated README formatting and added blame
squash a5f4a0d added cat-file

或

1
2
3

pick f7f3f6d changed my name a bit
s 310154e updated README formatting and added blame
s a5f4a0d added cat-file

当保存并退出编辑器时，Git 应用所有的三次修改然后将你放到编辑器中来合并三次提交信息：

# This is a combination of 3 commits.
# The first commit's message is:
changed my name a bit

# This is the 2nd commit message:

updated README formatting and added blame

# This is the 3rd commit message:

added cat-file

当你保存之后，你就拥有了一个包含前三次提交的全部变更的提交。
