使用pull和merge进行多人协作开发

1、master分支准备

# master分支
$ cd tm
$ git init 

touch a.txt
git add a.txt
git commit -m "add a.txt"

touch b.txt
git add b.txt
git commit -m "add b.txt"

touch c.txt
git add c.txt
git commit -m "add c.txt"

touch d.txt
git add d.txt
git commit -m "add d.txt"

touch e.txt
git add e.txt
git commit -m "add e.txt"

touch f.txt
git add f.txt
git commit -m "add f.txt"

$ git remote add origin https://gitee.com/zsx242030/sm.git

$ git push -u origin "master"

 * [new branch]      master -> master
Branch master set up to track remote branch master from origin.

$ git log --pretty=format:"%h: %cd %s" --graph

* 8e58180: Sat May 27 09:40:08 2023 +0800 add a.txt

2、A、B、C三个用户拉取代码并切换分支

# A用户branch_a分支
$ git clone https://gitee.com/zsx242030/sm.git

$ cd sm

$ git log --pretty=format:"%h: %cd %s" --graph
* 87d5c63: Sat May 27 09:40:12 2023 +0800 add f.txt
* 47e8b59: Sat May 27 09:40:10 2023 +0800 add e.txt
* c0547da: Sat May 27 09:40:10 2023 +0800 add d.txt
* 9c173bb: Sat May 27 09:40:09 2023 +0800 add c.txt
* 8c4a625: Sat May 27 09:40:09 2023 +0800 add b.txt
* 8e58180: Sat May 27 09:40:08 2023 +0800 add a.txt

$ git checkout -b branch_a
Switched to a new branch 'branch_a'

$ git branch -a
* branch_a
  master
  remotes/origin/HEAD -> origin/master
  remotes/origin/master

# B用户branch_b分支
$ git clone https://gitee.com/zsx242030/sm.git

$ cd sm

$ git log --pretty=format:"%h: %cd %s" --graph
* 87d5c63: Sat May 27 09:40:12 2023 +0800 add f.txt

* 8e58180: Sat May 27 09:40:08 2023 +0800 add a.txt

$ git checkout -b branch_b
Switched to a new branch 'branch_b'

$ git branch -a
* branch_b
  master
  remotes/origin/HEAD -> origin/master
  remotes/origin/master

# C用户branch_c分支
$ git clone https://gitee.com/zsx242030/sm.git

$ cd sm

$ git log --pretty=format:"%h: %cd %s" --graph
* 87d5c63: Sat May 27 09:40:12 2023 +0800 add f.txt

* 8c4a625: Sat May 27 09:40:09 2023 +0800 add b.txt
* 8e58180: Sat May 27 09:40:08 2023 +0800 add a.txt

$ git checkout -b branch_c
Switched to a new branch 'branch_c'

$ git branch -a
* branch_c
  master
  remotes/origin/HEAD -> origin/master
  remotes/origin/master

3、A用户添加文件和修改文件

# branch_a分支操作
$ echo branch_a > a.txt

$ echo branch_a_new > new.txt

# 暂存,防止pull的时候本地修改的代码被覆盖
$ git stash -u
warning: LF will be replaced by CRLF in new.txt.
The file will have its original line endings in your working directory.
Saved working directory and index state WIP on branch_a: 87d5c63 add f.txt

$ git status

nothing to commit, working tree clean

# 拉取远程master分支的代码
$ git pull origin master

10、使用commit代替stash解决pull时的代码覆盖

我们从 branch_a 分支上拉取 branch_d 分支：

$ git checkout -b branch_d origin/branch_a
Switched to a new branch 'branch_d'
Branch branch_d set up to track remote branch branch_a from origin.

$ git log --oneline
ddbfc0b (HEAD -> branch_d, origin/branch_a) branch_a | update a.txt | add new.txt
87d5c63 add f.txt
47e8b59 add e.txt
c0547da add d.txt
9c173bb add c.txt
8c4a625 add b.txt
8e58180 add a.txt

$ ls
a.txt  b.txt  c.txt  d.txt  e.txt  f.txt  new.txt

修改 a.txt 和 e.txt 文件，删除 b.txt 文件：

echo branch_d > a.txt
echo branch_d > e.txt
rm b.txt

$ git status
On branch branch_d
Your branch is up-to-date with 'origin/branch_a'.

Changes not staged for commit:
  (use "git add/rm <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

        modified:   a.txt
        deleted:    b.txt
        modified:   e.txt

no changes added to commit (use "git add" and/or "git commit -a")

# 提交
$ git add .

$ git commit -m "branch_d | update a.txt | update b.txt | update e.txt"
[branch_d 75dc0b6] branch_d | update a.txt | update b.txt | update e.txt

# pull远程分支
