前言

git是程序员常用的工具，用来进行代码的管理工作。大家可以看下git的官网。接下来这几篇我们就一起学习git。感兴趣的可以看下面几篇。
1. git的使用（一） —— git的配置（一）

写在前面：这个日子，对于很多家庭都会很难受吧，有些亲人再也回不来了。

git命令总览

我们在终端中输入git，然后回车，系统就会提示所有的git指令。

xxxMacBook-Pro ~ % git 
usage: git [--version] [--help] [-C <path>] [-c <name>=<value>]
           [--exec-path[=<path>]] [--html-path] [--man-path] [--info-path]
           [-p | --paginate | -P | --no-pager] [--no-replace-objects] [--bare]
           [--git-dir=<path>] [--work-tree=<path>] [--namespace=<name>]
           [--super-prefix=<path>] [--config-env=<name>=<envvar>]
           <command> [<args>]

These are common Git commands used in various situations:

start a working area (see also: git help tutorial)
   clone             Clone a repository into a new directory
   init              Create an empty Git repository or reinitialize an existing one

work on the current change (see also: git help everyday)
   add               Add file contents to the index
   mv                Move or rename a file, a directory, or a symlink
   restore           Restore working tree files
   rm                Remove files from the working tree and from the index
   sparse-checkout   Initialize and modify the sparse-checkout

examine the history and state (see also: git help revisions)
   bisect            Use binary search to find the commit that introduced a bug
   diff              Show changes between commits, commit and working tree, etc
   grep              Print lines matching a pattern
   log               Show commit logs
   show              Show various types of objects
   status            Show the working tree status

grow, mark and tweak your common history
   branch            List, create, or delete branches
   commit            Record changes to the repository
   merge             Join two or more development histories together
   rebase            Reapply commits on top of another base tip
   reset             Reset current HEAD to the specified state
   switch            Switch branches
   tag               Create, list, delete or verify a tag object signed with GPG

collaborate (see also: git help workflows)
   fetch             Download objects and refs from another repository
   pull              Fetch from and integrate with another repository or a local branch
   push              Update remote refs along with associated objects

'git help -a' and 'git help -g' list available subcommands and some
concept guides. See 'git help <command>' or 'git help <concept>'
to read about a specific subcommand or concept.
See 'git help git' for an overview of the system.

git config 查看配置信息

config 配置有system级别 global（用户级别）和local（当前仓库）三个设置先从system -> global -> local 底层配置会覆盖顶层配置，分别使用--system/global/local 可以定位到配置文件。

查看系统config

git config --system --list

查看当前用户（global）配置

git config --global  --list

下面是我的电脑的一个输出示例

xxx@xxxMacBook-Pro ~ % git config --global --list
core.excludesfile=/Users/xxx/.gitignore_global
difftool.sourcetree.cmd=opendiff "$LOCAL" "$REMOTE"
difftool.sourcetree.path=
mergetool.sourcetree.cmd=/Applications/Sourcetree.app/Contents/Resources/opendiff-w.sh "$LOCAL" "$REMOTE" -ancestor "$BASE" -merge "$MERGED"
mergetool.sourcetree.trustexitcode=true
user.name=xxx
user.email=xxx@xxx.com
commit.template=/Users/xxx/.stCommitMsg
http.version=HTTP/1.1

查看当前仓库配置信息

git config --local    --list

设置用户名和邮箱

git config --global user.name "xxx"
git config --global user.email "xxx@xxx.com"

直接打开局部git config文件

在一个git仓库里，点一下command + shift + .命令，然后就可以看见git文件夹下一级里有一个config的文件夹

直接打开

可以看见，就是core、remote和branch信息等。

直接打开系统git config文件

直接执行command + shift + .命令

其实，系统级别的config文件在如下路径里。

// xxxx就是电脑用户名
/Users/xxxx/.gitconfig

我们直接打开

创建新仓库 - Create a new repository

git clone git@git.xxx.git
cd 一个本地文件夹
touch README.md
git add README.md
git commit -m "add README"
git push -u origin master

已经存在的文件夹推送到远端 - Existing folder

cd existing_folder
git init
git remote add origin git@git.xxx.git
git add .
git commit -m "Initial commit"
git push -u origin master

已经存在的git仓库推送到远端 - Existing Git repository

cd existing_repo
git remote rename origin old-origin
git remote add origin git@git.xxx.git
git push -u origin --all
git push -u origin --tags
