<h1>mac os 系统目录结构</h1>
<div class="a-content">
<div class="a-content-text">
<p>最近使用 <code>nginx</code> 需要修改配置文件,虽然文档对路径写的非常清楚,<code>ctrl + c ctrl + v</code> 就可以快速找到需要的文件,但是加上之前使用过程中的困惑,索性就整理下 系统中 各个目录的作用吧,使得以后使用的更得心应手吧<br/>
🚗🚗🚗🚗🚗🚗🚗🚗</p>
<h2 id="toc_0">目录结构</h2>
<p>首先看下根目录 都有哪些目录吧<br/>
<img src="media/15578321968662/15578327680843.jpg" alt="" style="width:567px;"/></p>
<p>因为mac OS 属于类 Unix 系统,所以 mac OS 目录 = Unix 系统通用目录 + 独有目录,下面将分别介绍。</p>
<h2 id="toc_1">Unix 通用目录</h2>
<ul>
<li><code>/bin</code> 传统 unix 命令的存放目录,如 ls,rm, mv 等</li>
<li><code>/sbin</code> 传统 unix 管理类命令存放目录,如 <code>fdisk</code>,<code>ifconfig</code>等</li>
<li><code>/usr</code> 第三方程序安装目录</li>
<li><code>/usr/bin, /usr/sbin,/usr/lib</code>, 其中<code>/usr/lib</code>目录中存放了共享库(动态链接库)</li>
<li><code>/dev</code> 设备文件存放目录,如 代表硬盘的 <code>/dev/disk0</code></li>
<li><code>/etc</code> 标准unix系统配置文件存放目录,如用户密码文件 <code>/etc/passwd</code>。此目录实际指向 <code>/private/etc</code> 的链接</li>
<li><code>/tmp</code> 临时文件存放目录,其权限为所有人任意读写。此目录实际指向 <code>/private/tmp</code> 的链接</li>
<li><code>/var</code> 存放经常变化的文件,如日志文件。此目录实际指向 <code>/private/var</code>的链接</li>
</ul>
<h2 id="toc_2">mac OS 独有目录</h2>
<ul>
<li><code>/Applications</code> 应用程序目录,默认所有的GUI应用程序都安装在这里</li>
<li><code>/Library</code> 系统的数据文件、帮助文件、文档等等</li>
<li><code>/Network</code> 网络节点存放目录</li>
<li><code>/System</code> 只包含一个名为 <code>Library</code> 的目录,这个字目录中存放了系统的绝大部分组件,如各种<code>framework</code>,以及内核模块,字体文件等等</li>
<li><code>/Users</code> 存放用户的个人资料和配置。每个用户有自己的单独目录</li>
<li><code>/Volumes</code> 文件系统挂载点存放目录</li>
<li><code>/cores</code> 内核转储文件存放目录。当一个进程奔溃时,如果系统允许则会产生转储文件</li>
<li><code>/private</code> 里面的字目录存放了 <code>/tmp,/var,/etc</code> 等链接目录的目标目录</li>
</ul>

<p>当你想更正别人的仓库时,要走一个流程</p>
<ol>
<li>先fork 别人的仓库,不会有人让你直接改原仓库的</li>
<li>clone 到本地分支,做一些bug fix</li>
</ol>
<pre><code class="language-shell">git clone https://github.com bootstrap
cd bootstrap
git checkout -b test-pr
git add . && git commit -m "test-pr"
git push origin test-pr
</code></pre>
<ol>
<li>发起 pull request给原仓库,让他看到你修改的bug 点击 仓库 compare & pull request 按钮</li>
<li>原仓库 review 这个bug,如果正确的话,就会merge到他自己的项目中 至此 整个 pull request的过程就结束了</li>

<h1>为什么可以使用 // 代替 http:// 或 https://</h1>
<div class="a-content">
<div class="a-content-text">
<p><code>//</code> 顾名思义:😃 两个双斜杠</p>
<p>🤨🤨 严肃点</p>
<p><code>//</code> 是缺省协议的写法,是指协议自动采用当前页面的协议</p>
<p>即: 当前页面是 <code>http</code>,则采用<code>http</code>协议访问<br/>
当前页面是 <code>https</code>,则采用<code>https</code>协议访问,一般是使用在内链中</p>
<h2 id="toc_0">优点</h2>
<ol>
<li>根据用户打开的页面自适应资源的请求方式</li>
<li>可以阻止在 <code>https</code> 的页面,浏览器会默认组织 非<code>https</code>内容的情况</li>
</ol>
<h2 id="toc_1">缺点</h2>
<ol>
<li>本地调试时,使用的协议是文本协议<code>file://</code></li>
