02 | 安装Git
1
https://git-scm.com/book/zh/v2/%E8%B5%B7%E6%AD%A5-%E5%AE%89%E8%A3%85-Git
-
查看安装版本
git --version
03 | 使用Git之前需要做的最小配置
- 配置 user 信息
主要是为了在commit的时候能够添加上提交者的相关信息，方便在代码审查的时候知道提交人是谁，方便联系。
git config --global user.name "zhangshaopo"
git config --global user.email "ragpo_24@163.com"
- 有三种级别的user信息，缺省等同于 local。
git config --local # local只对仓库有效
git config --global # global对登录⽤户所有仓库有效
git config --system # system对系统的所有⽤户有效，一般不用
- 显示 config 的配置，加 --list
git config --list --local
git config --list --global
git config --list --system
- 清除，--unset
git config --unset --local user.name
git config --unset --global user.name
git config --unset --system user.name
- 优先级
local > global > system
04 | 创建第一个仓库并配置local用户信息
1
- 创建一个库
git init git-learning-1
- 配置 user 信息
cd git-learning-1
git config --local user.email "ragpo_24@163.com"
git config --local user.name "apo"
- 创建一个README.md文件，内容如下：
line1
- 查看状态
$ git status
On branch master
No commits yet
Untracked files:
(use "git add <file>..." to include in what will be committed)
README.md
nothing added to commit but untracked files present (use "git add" to track)
- 添加到占存区
git add README.md
- 查看状态
$ git status
On branch master
No commits yet
Changes to be committed:
(use "git rm --cached <file>..." to unstage)
new file: README.md
- commit
$ git commit -m"add README.md"
[master (root-commit) beab99b] add README.md
1 file changed, 1 insertion(+)
create mode 100644 README.md
- 查看状态
$ git status
On branch master
nothing to commit, working tree clean
- 查看日志
可以看到Author是我们设置的名称和邮件
$ git log
commit beab99bb7d4887a05e322483e65db7e569af2bce (HEAD -> master)
Author: zhangshaopo <ragpo_24@163.com>
Date: Wed Jun 3 17:51:13 2020 +0800
add README.md
add README.md
05 | 通过几次commit来认识工作区和暂存区
1
- 添加两个文件a和b
$ git status
On branch master
Untracked files:
(use "git add <file>..." to include in what will be committed)
a
b
$ git add a b
$ git status
On branch master
Changes to be committed:
(use "git restore --staged <file>..." to unstage)
new file: a
new file: b
- 用 git restore --staged 将通过add添加到暂存区的a文件进行回退
git restore --staged a
- 查看状态
$ git status
On branch master
Changes to be committed:
(use "git restore --staged <file>..." to unstage)
new file: b
Untracked files:
(use "git add <file>..." to include in what will be committed)
a
- 将a和b文件进行commit提交
$ git add a
$ git commit -m"add a and b"
[master 8bfc512] add a and b
2 files changed, 2 insertions(+)
create mode 100644 a
create mode 100644 b
- 修改a和b的内容，通过 git add -u 同时添加多个文件到暂存区
$ git status
On branch master
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git restore <file>..." to discard changes in working directory)
modified: a
modified: b
no changes added to commit (use "git add" and/or "git commit -a")
$ git add -u
$ git status
On branch master
Changes to be committed:
(use "git restore --staged <file>..." to unstage)
modified: a
modified: b
$ git commit -m"modify a and b"
[master a7ec957] modify a and b
2 files changed, 2 insertions(+), 2 deletions(-)
$ git status
On branch master
nothing to commit, working tree clean
06 | 给文件重命名的简便方法
以下使用旧的方法，将a命名为aa
$ mv a aa
# zhangshaopo @ zhangshopodeMBP in ~/git-learning-1 on git:master x [21:38:26]
$ ll

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

$ git commit -m"rename a to aa"
[master 19954dc] rename a to aa
1 file changed, 0 insertions(+), 0 deletions(-)
rename a => aa (100%)

10 | commit、tree和blob三个对象之间的关系
1
一次commit就对应着对当前时间仓库内的所有文件做了一次快照；一次commit对应着一个tree，tree类似文件夹，一个tree下面又可以包含多个tree，tree下面可以包含文件，也就是blob，但是blob没有具体名字，因为git的存储机制是基于相同文件的内容就认为是同一个blob，在有多个文件时，就能节省实际的存储空间。
11 | 小练习：数一数tree的个数
1
一次commit，至少包含本身一个tree，因为又包含一个目录doc，所以又会有个tree，doc下面包含一个文件，也是就blob，所以一共有2个tree，1个blob。
12 | 分离头指针情况下的注意事项
分离头指针说的是当前我们的工作不在具体的某个分支上进行，而是在一个没有分支的状态下工作，这种状态是同样可以commit，一般的用处就是仅仅做个测试验证，可以随时不要，只需要执行git checkout某个分支就可以丢弃了，但是git会提示你，是否需要将在分离头指针情况下的commit生成一个分支。分离头指针一般是基于某个commit生成的。

$ git checkout a7ec957015686e3de8
Note: switching to 'a7ec957015686e3de8'.
You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.
If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:
git switch -c <new-branch-name>
Or undo this operation with:
git switch -
Turn off this advice by setting config variable advice.detachedHead to false

13 | 进一步理解HEAD和branch
head可以指向某个branch或者某个tag，其实具体的就是某个commit，因为一个branch的状态会随着commit的提交不断发生变化，所以head可以直接指代某个commit。比如通过git diff来比较不同commit之间的差异时，可以使用commit id，也可以使用head，如果使用head的话，默认是head指代的就是当前分支的最新commit。

使用HEAD来指代当前分支commit，HEAD1或者HEAD~1指代上一个commit，HEAD^或者HEAD~2指代上上一个commit.
14 | 怎么删除不需要的分支？
使用git branch -d或者git branch -D进行删除分支，-D是强制确认删除。

15 | 怎么修改最新commit的message？
通过git commit --amend命令修改当前的commit的message信息。
16 | 怎么修改老旧commit的message？
通过使用git rebase -i 指定commit的父commit id，进入一个文件交互框，然后将pick修改为reword/r，然后保存退出，会再进行一个文件交互框，这个时候修改commit信息，再保存退出。

34 | 不同人修改了不同文件如何处理？
我们在别人修改并且push之前，已经pull/fetch到本地后，别人在修改了一个文件A，push到GitHub，此时我们在本地修改文件B，在push的时候会报错，那么就需要通过使用git fetch，然后再git merge，最后git push。git pull其实等于git fetch和git merge两个操作，完成本地与远端的同步，如果相同文件
35 | 不同人修改了同文件的不同区域如何处理？
这个其实和上个没有太大区别，因为修改的地方不一样，所以会在merge的时候自动合并。
36 | 不同人修改了同文件的同一区域如何处理？
首先还是得先pull在GitHub上最新的代码，然后会提示merge失败的地方，修改对应的文件，然后再add commit，然后push。
37 | 同时变更了文件名和文件内容如何处理？
在别人修改了文件名以及内容，并且push到GitHub后，我们在本地修改了原始文件，push的时候会报错，通过使用git pull就能将文件名同步并且merge文件内容。
38 | 把同一文件改成了不同的文件名如何处理？
同理，先git pull下来，然后会提示文件冲突，本地会出现别人修改后的文件名文件，再通过git status根据提示add和rm文件，最后push。
39 | 禁止向集成分支执行push -f操作
悠着点用。GitHub和gitlab提供禁止push -f的操作配置。

- create a merge commit: Beijing的分支会连接到master那里。
2
- squash and merge: 将北京的合并到master，会将三个commit合并成一个merge到master上，master会多了一个commit，北京本身没有变化。

- rebase and merge: 将北京的三个commit合并到master上，北京本身没有变化。

补充
直接在全局设置
git config --global http.sslVerify "false"
当然是一个方法，但此方法的不足在于会玷污全局配置。下面介绍一个即方便又不玷污全局配置的方法。
推荐的方法
Windows
打开 PowerShell
$Env:GIT_SSL_NO_VERIFY="true"
git clone https://abc.dev/user/repo.git
然后 cd 进去
cd .\repo\
设置不验证证书
git config http.sslVerify "false"
Linux
打开终端
export GIT_SSL_NO_VERIFY="true"
git clone https://abc.dev/user/repo.git
然后 cd 进去
cd ./repo/
设置不验证证书
git config http.sslVerify "false"
