Git Shell使用笔记

1，首次打开Git shell错误（以前打开过gethub客户端）

警告: git command could not be found. Please create an alias or add it to your
PATH.
警告: Could not find ssh-agent

解决方法

1，close Git Shell,关闭Git Shell客户端
2，open GitHub and let it do some post installation. 这步骤是打开GitHub客户端，把里面的无效链接删除啥的,
3，Open Git Shell again and you should be fixed.打开Git Shell客户端。

2，在个人电脑f盘建git名文件夹，GitShell中 cd f:,cd git之后，在网站上new Repositoriy之后，copy项目地址，命令：

git clone https://github.com/lkdghzh/MyBackUp.git

3，git status的时候报错误,因为需要初始化：

fatal: Not a git repository (or any of the parent directories): .git

解决办法：提示说没有.git这样一个目录。输入git init，之后git shell命令行开头就从F:\git>变成了F:\git [master +1 ~0 -0 !]>

解释：git status命令可以列出当前目录所有还没有被git管理的文件和被git管理且被修改但还未提交(git commit)的文件

其实不对,我们需要继续cd respositiry的文件夹，
如果不继续cd respositiry的文件夹的话，做了git init,在respositiry的文件夹的同级会多一个.git文件夹,
respositiry的文件夹的子文件夹还有一个.git，就不对了嘛~

clone之后的文件夹名是假如是demo，.git文件是在demo文件夹里面的。我们需要继续cd:demo，然后git status就不会报上述错误了！
这样的demo文件夹的文件(.html.css)、文件夹(js css)就下载下来了。

3.1Untracked files:git怎样删除未监视的文件untracked files

用 git clean

# 删除 untracked files
git clean -f

# 连 untracked 的目录也一起删掉
git clean -fd

# 连 gitignore 的untrack 文件/目录也一起删掉 （慎用，一般这个是用来删掉编译出来的 .o之类的文件用的）
git clean -xfd

# 在用上述 git clean 前，墙裂建议加上 -n 参数来先看看会删掉哪些文件，防止重要文件被误删
git clean -nxfd
git clean -nf
git clean -nfd

4,设置/查看用户名、邮箱

git config --global user.name "lkdghzh"
git config --global user.email "416960428@qq.com"

查看的时候把后面的用户名或者邮箱名去掉就ok

F:\git [master +2 ~0 -0 !]>
+ = Added files
~ = Modified files
- = Removed files
! = Conflicted files

后面数字我觉得应该是个数。

git 上传到网站中文编码

分支：

1查看本地分支

git branch

* master

2查看远程本地分支

git branch -a

* master
 remotes/origin/HEAD -> origin/master
 remotes/origin/master

3本地创建分支

git branch new_branch

git branch
* master
  new_branch

4本地分支推到远程分支

git push 时候fatal: The current branch new_branch has no upstream branch

$ git push
fatal: The current branch new_branch has no upstream branch.
To push the current branch and set the remote as upstream, use

    git push --set-upstream origin new_branch
