linux命令之git
git其实是一种多人开发项目时候的版本控制系统，是由LINUX之父Linus开发的，与SVN最大的区别在于可以支持离线操作。首先安装：我用的网易的yum源http://mirrors.163.com/centos/6/os/x86_64/ 然后yum install git -y
[*]Git初始化
#git --version 查看git版本
#git config --global user.name dangwanqiang 当前用户姓名和邮箱
#git config --global color.ui true 在git输出中开启颜色显示
#git config --list

user.name=dangwanqiang
user.email=goodang517@163.com
color.ui=true
实际也是写入文件中去
#cat ~/.gitconfig

name = dangwanqiang
email = goodang517@163.com
ui = true
[*]建立一个工作目录
#git init github
#cd github
#ls -A
.git 可以看到隐藏的目录.git(Git版本库，repository)
[*]在工作目录下的建立操作
三部曲：1.init2.add3.commit
# touch READ.txta.py //创建自己的工作文件
# git status

# Untracked files: //未添加到版本库的文件
# (use "git add <file>..." to include in what will be committed)
#
#READ.txt
#a.py
nothing added to commit but untracked files present (use "git add" to track)
# git add a.py //将a.py加到版本库
