写代码经常需要搜索一些命令、函数或者编程语言语法的问题，都可以通过其快速搜索而得到示例，小能手呀。 终端，使用 curl 即可启动： curl cheat.sh curl cht.sh 比如UNIX/Linux 命令： curl cheat.sh/tar curl cht.sh/curl curl https://cheat.sh/rsync curl https://cht.sh/tr 模糊查找，比如想查看如何建立快照，可使用～Keyword 的形式来查询： curl cht.sh/~snapshot 各种语言： curl cht.sh/go/Pointers curl cht.sh/scala/Functions curl cht.sh/python/lambda 具体支持语言列表用list查询： curl cht.sh/go/:list 各种问题解决方式，语言/问题描述： ...
环境：centos7.4 将对应的程序所在路径加到 Path 环境变量里，可以实现在任意地方执行脚本的效果。Bash 运行后会先加载 .bashrc 文件，所以可以把脚本路径添加到 .bashrc 文件。 假设，脚本放在 /home/opc/scripts 目录下，脚本名称是 aliyundrive-cli_linux_amd64。 运行下面代码将其加到 .bashrc： export PATH="/home/opc/scripts:$PATH" 再使用 source 命令使修改生效： $ source ~/.bashrc 完事
页眉(header)或者页脚(footer)引入js文件，（可将go-top.js其中的图片地址改成你自己自定义的）： <script src="https://cdn.jsdelivr.net/gh/jquery/jquery@3.2.1/dist/jquery.min.js"></script> <script src="<?php $this->options->themeUrl('go-top.js');?>"></script> <a href="#" class="cd-top faa-float animated animate-bounce-up" style="top: -900px;"></a> go-top.js代码如下： var scrolltotop={ //startline: Integer.
