Git 合并多个commit

使用git rebase -i来合并多个commit到一个新的commit内

D:\Git\learngit (master)
$ git l
* dee2b21 - (HEAD -> master) ddd (1 second ago) | hongda
* ff20d90 - ccc (23 seconds ago) | hongda
* 931ebca - bbb (55 seconds ago) | hongda
* 7af981e - aaa (2 minutes ago) | hongda
* 9f015b3 - clean aa.txt (2 minutes ago) | hongda
* e4395d8 - eee (80 minutes ago) | hongda

合并最上面的4个commit到9f015b3中，并生成一个新的commitid

想要合并1-5条，有两个方法

 1.从HEAD版本开始往过去数3个版本

git rebase -i HEAD~5

 2.指名要合并的版本以前的版本号

git rebase -i e4395d8

请注意ff4cda8这个版本是不参与合并的，能够把它当作一个坐标

2.执行了rebase命令以后，会弹出一个窗口，头几行以下：

pick 9f015b3 clean aa.txt
pick 7af981e aaa
pick 931ebca bbb
pick ff20d90 ccc
pick dee2b21 ddd

# Rebase e4395d8..dee2b21 onto e4395d8 (5 commands)
#
# Commands:
# p, pick = use commit
# r, reword = use commit, but edit the commit message
# e, edit = use commit, but stop for amending
# s, squash = use commit, but meld into previous commit
# f, fixup = like "squash", but discard this commit's log message
# x, exec = run command (the rest of the line) using shell
# d, drop = remove commit
#
# 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

2.将pick改成squash或者s,以后保存并关闭文本编辑窗口便可。改完以后文本内容以下：

pick 9f015b3 clean aa.txt
s 7af981e aaa
s 931ebca bbb
s ff20d90 ccc
s dee2b21 ddd

3.而后保存退出，Git会压缩提交历史，若是有冲突，须要修改，修改的时候要注意，保留最新的历史，否则咱们的修改就丢弃了。修改之后要记得敲下面的命令：

git aa
git rebase --continue

若是你想放弃此次压缩的话，执行如下命令：

git rebase --abort

成功的话，弹出

# This is a combination of 5 commits.
# This is the 1st commit message:

clean aa.txt

# This is the commit message #2:

aaa

# This is the commit message #3:

bbb

# This is the commit message #4:

ccc

# This is the commit message #5:

ddd

# Please enter the commit message for your changes. Lines starting
# with '#' will be ignored, and an empty message aborts the commit.
#
# Date:      Wed Feb 7 15:47:23 2018 +0800
#
# interactive rebase in progress; onto e4395d8

修改clean aa.txt 为 clean aa.txt modify,保存并退出

执行结果:

$ git rebase -i e4395d8
[detached HEAD 76efa0a] clean aa.txt modify
 Date: Wed Feb 7 15:47:23 2018 +0800
 1 file changed, 5 insertions(+), 2 deletions(-)
Successfully rebased and updated refs/heads/master.

从新查看历史记录：

$ git l
* 76efa0a - (HEAD -> master) clean aa.txt modify (2 minutes ago) | hongda
* e4395d8 - eee (86 minutes ago) | hongda
