Git基础命令学习
参考链接：https://www.cnblogs.com/wangwenhui/p/10546635.html
以前用 IDE 的时候只知道一个劲的 commit，现在该好好回想一下 Git 那些最基础的命令了。
Git的三种状态
已提交（commited），已修改（modified）和已暂存（staged）
1. 已提交（commited）：表示数据已经安全的保存在本地数据库中。
2. 已修改（modified）：已经修改了文件，但是还没有保存到本地数据库中。
3. 已暂存（staged）：表示对一个已经修改的文件的当前版本做了标记，使其包含在了下次的提交中。
基本的Git工作流程
1. 在工作目录中修改文件。（modified）
2. 暂存文件，将文件的快照放入暂存区。（staged）
3. 提交更新。找到暂存区域的文件，将快照永久性的存储到Git仓库。（commited）
git init : 初始化Git仓库。 该命令会在你当前所在的目录创建一个.git文件夹
git add . :将当前所在目录中的所有文件加入到暂存区
git add README.md : 将README.md文件加入到暂存区（让git去跟踪它）
git commit -m "Initial commit" : 将暂存区的文件提交到Git仓库
git clone https://github.com/2392863668/GitTest.git
工作目录中的文件主要有两种状态：已追踪（tracked）和未追踪（untracked）。
1.已追踪（tracked）：已追踪的文件指的是已经被纳入到版本控制的文件。已追踪的这些文件又可能处于已修改（modified），未修改（unmodified），已暂存（staged）的状态。
当你克隆了一个远程仓库到本地的时候，工作目录中所有的文件都是已追踪的文件，而且都是处于未修改的状态。
2.未追踪（untracked）：未追踪的文件表示不被纳入版本控制的文件，除了已追踪的文件之外所有的文件都是未追踪文件。例如当你克隆了一个项目到本地之后，你在本地的项目中新添加了一个文件，那么这个文件就是未追踪的状态。
1.未追踪的文件（Untracked）在 git add 之后会变成已暂存（staged）状态。
2.未修改的文件（Unmodified）在被修改编辑之后会变成已修改（modified）状态。
3.已修改（modified）的文件在 git add之后会变成已暂存（staged）状态。
4.已暂存的文件（staged）在 git commit 之后会变成未修改（Unmodified）状态。
5.未修改的文件（Unmodified）在 git rm 之后会变成未跟踪（Untracked）状态(注意git rm会删除掉指定的文件)。git status

nothing to commit, working tree clean
git diff
1. git diff ：查看尚未暂存的文件更新了哪些部分。
2. git diff --staged ：查看已暂存的文件更新了哪些部分。

git add
当在工作目录新建一个文件，运行 git status ，会显示这个文件是untracked状态。这时候需要使用 git add 将这个文件加入暂存区，也就是告诉Git需要去跟踪这个文件。git add 使用文件或者目录的路径作为参数；如果参数是目录的路径，那么将该目录下所有的文件加入暂存区，Git将会跟踪这个目录下面的所有文件。
如果文件是tracked状态，当修改了Git追踪的一个文件之后，运行 git status 会看到 Changes not staged for commit ，说明已跟踪的文件发生了变化但是还没有被加入到暂存区，这时候需要运行 git add 将该文件放入暂存区。

nothing to commit, working tree clean
git commit
在暂存区准备完毕之后，就可以commit了。注意：在提交之前一定要确认还有什么没有修改过的活新建的文件还没有 git add 过，否则commit的时候不会记录这些还没暂存起来的变化，这些修改过的文件只会保留在本地磁盘（也就是工作区）。在每次提交之前，可以使用 git status 查看一下，文件是不是已经都暂存起来了。
1. git commit 如果不指定-m参数，那么git会打开一个编辑器，让你输入提交信息。
2. git commit -m
3. git commit -a -m
commit记录的是放在暂存区域的快照，每一次提交操作都是对项目做一次快照，以后可以回到这个状态，或者进行比较。

git rm
1. git rm
执行以下命令：删除一个文件。
$ git rm
$ git commit -m Administrator@PC-20200713AJJH MINGW64 /d/MyProject/Python/GitTest (master)
$ git rm d.txt
rm 'd.txt'
Administrator@PC-20200713AJJH MINGW64 /d/MyProject/Python/GitTest (master)
$ git status
On branch master
Your branch is up to date with 'origin/master'.
Changes to be committed:
(use "git reset HEAD ..." to unstage)
deleted: d.txt
Administrator@PC-20200713AJJH MINGW64 /d/MyProject/Python/GitTest (master)
$ git commit -m "delete d.txt"
[master 32b9c4e] delete d.txt
1 file changed, 4 deletions(-)
delete mode 100644 d.txt
如果被删除的文件修改过，而且已经被放入了暂存区，那么需要加上 -f 参数，强制删除。这是一种安全特性，用于防止删除还没有被添加快照的数据，这种数据无法被Git恢复。
2. git rm --cached
如果你只是想从暂存区删除文件，但是工作区的文件保持不变（将文件保存在磁盘），也就是说将文件保存在磁盘但是不想让 Git 进行跟踪，使用如下命令即可：
$ git rm --cached Administrator@PC-20200713AJJH MINGW64 /d/MyProject/Python/GitTest (master)
$ vi test.txt # 新行添加 hello world

modified: test.txt
no changes added to commit (use "git add" and/or "git commit -a")

$ git rm --cached test.txt
rm 'test.txt'
Administrator@PC-20200713AJJH MINGW64 /d/MyProject/Python/GitTest (master)
$ git status # 显示文件 test.txt 为 Untracked files

git mv
可以使用 git mv 来将文件重命名（在被 tracked 的情况下），会将 oldFile 重新命名为 newFile 。
$ git mv
这条命令会：1.将文件改名；2.将改名之后的文件add进暂存区。等价于下面三条命令。
$ mv oldFile newFile
$ git rm oldFile
$ git add newFile Administrator@PC-20200713AJJH MINGW64 /d/MyProject/Python/GitTest (master)
$ git add test.txt

git commit --amend
有时候我们在提交完成之后才发现有几个文件没有提交，或者发现提交信息填写错了，这时候可以使用 git commit --amend 尝试重新进行提交。
1.这条命令会将暂存区中的文件进行提交
2.在提交的时候可以修改上一次commit的提交信息
3.最终只有一次commit，第二次的commit会替代第一次的commit(也就是只会产生一个commit节点，使用 git log 会看到上一次的commit不见了，被这次的新commit替换)

当你对一个文件进行了修改，还没有add进暂存区，你想要放弃所有的修改，将文件恢复到没有修改之前的样子，这时候可以使用 git checkout --

强制拉取覆盖本地
如果你想以远程仓库的版本内容为准，丢弃本地所有修改（当然，本地的 untracked file 不属于版本控制的范围，不会受到这条命令的影响），又不想删除本地仓库以后再次 git clone，就按下边这么做吧。
git fetch --all && git reset --hard origin/master && git pullgit rebase -i HEAD~2
如果你想把本地的多个 commit 合并成一个，就用这个吧（从 git log 可以看到，两次 commit 变成了一个，两次 commit 所做的修改也反映到了一个 commit 上）：
[root@master GitTest]# git status
# On branch master
# Your branch is ahead of 'origin/master' by 2 commits.
# (use "git push" to publish your local commits)
#
nothing to commit, working directory clean
[root@master GitTest]# git rebase -i HEAD~2
pick 1a6cb23 add hello in new line of looking.txt
squash 636b8a7 add world in new line of looking.txt
# Rebase cd3e336..636b8a7 onto cd3e336
#
# 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
#
# These lines can be re-ordered; they are executed from top to bottom.
#
# If you remove a line here THAT COMMIT WILL BE LOST.

git tag
1. git tag
git tag 会按照字母顺序列出所有的标签
git tag -l 'v1.0*' 列出v1.0系列的标签。
[root@master GitTest]# git tag
v1.0
v1.1
2. git show
显示标签的相关信息，比如被打在了哪个 commit 上。
[root@master GitTest]# git show v1.1

3. git push origin
如果想将本地的tag上传到远程仓库，则必须显示的将tag push上去。默认情况下 git push 是不会将tag上传到远程仓库的。一次推送许多标签： git push origin --tags 会将不在远程仓库的所有标签上传上去。
[root@master GitTest]# git tag -a v1.2 -m "version 1.2"
[root@master GitTest]# git tag
v1.0
v1.1
v1.2
[root@master GitTest]# git push origin v1.2

To [email protected]:2392863668/GitTest.git
* [new tag] v1.2 -> v1.2
4. git tag -d
[root@master GitTest]# git tag -d v1.2
Deleted tag 'v1.2' (was d332b35)
[root@master GitTest]# git push origin :refs/tags/v1.2
To [email protected]:2392863668/GitTest.git
- [deleted] v1.2
git remote
1. git remote -v
查看远程URL，如果有多个的话会都列出来（比如可能会同时 push 到多个仓库的话，就有多个 push 的 URL）
[root@master GitTest]# git remote -v
origin [email protected]:2392863668/GitTest.git (fetch)
origin [email protected]:2392863668/GitTest.git (push)
[root@master GitTest]#
2. git push origin master
注意：只有当你对远程仓库具有写入权限的时候，这条命令才会生效。当你在与别人合作开发一个项目的时候，如果，他们先推送了自己的代码到了远程仓库，你在直接进行推送，会被拒绝，你必须先将他们的代码先拉取下来进行合并（merge or rebase）之后，才能进行推送。
[root@master GitTest]# git push origin master
Everything up-to-date
3. git remote show origin
[root@master GitTest]# git remote show origin
* remote origin
Fetch URL: [email protected]:2392863668/GitTest.git
Push URL: [email protected]:2392863668/GitTest.git
HEAD branch: master
Remote branch:
master tracked
Local branch configured for 'git pull':
master merges with remote master
Local ref configured for 'git push':
master pushes to master (up to date)
4. git remote rm
移除远程仓库（这块我就不多尝试了）
[root@master GitTest]# git remote rm origin
[root@master GitTest]# git remote add origin [repo-url]
