powershell是运行在windows平台的脚本，而bash是运行在linux平台的脚本
现在bash能做的事情，PowerShell也能做，PowerShell的强大之处是它可以管理windows服务器（特别是域domain），现在的开源PowerShell 也可以管理Linux和Mac（通过PSRP）。
下载最新的PS程序
安装后它会有powershell和它的开发IDE工具，ISE,非常不错！
一、进行powershell的程序
二、创建脚本，简单的Helloworld.ps1
任务的自动化是以程序文件或者可执行脚本文件为基础的，PowerShell也支持将命令列表做成脚本文件来执行。以下是Helloworld.ps1脚本文件的内容：
淄博分类信息港程序seo特别版
下载
seo特别版程序介绍：注意：普通用户建议使用淄博分类信息港程序普通版本。主要针对seo需要增加了自定义功能：自定义文件路径；自定义文件名；自定义关键字。这些功能的作用，只有自己体会了。以下是淄博分类信息港程序的介绍：淄博分类信息港程序一套现成的城市分类信息网站发布系统。发布管理房屋、人才、招租、招聘、求购、求租、搬迁、运输、二手交易、招生培训、婚介交友等各类信息的发布和查询。淄博分类信息港发布程序
$a = "Hello World!"$a echo $a > a.txt dir a.txt
Helloworld.ps1脚本文件的执行情况结果如下：
PS E:\>.\Helloworld.ps1 --注意在执行它时要加.\，表示当前上当下的文章，类似于centos里的文件执行方法
Hello world!Directory: E:\Mode LastWriteTime Length Name ---- ------------- ------ ---- -a--- 5/30/2017 4:56 PM 16 a.txt
下面是在eShopOnContainers上的一个例子，分别用ps和bash实现了程序的部署
#!/bin/bash

# WE DON'T NEED DOCKER BUILD AS WE CAN RUN "DOCKER-COMPOSE BUILD" OR "DOCKER-COMPOSE UP" AND IT WILL BUILD ALL THE IMAGES IN THE .YML FOR US自己感觉，这两个东西在以后的程序部署上都会发挥各自强大的力量！
