为了解技术思路,研究了一下powershell.
整个开发与部署过程如下:
1.下载windowsxp-kb926139-v2-x86-enu
安装powershell环境;
2.按照代码要求,写一个简单的脚本;
3. 运行powershell时,同 bat是有区别的.注意以下方法:
1) 解除限制:
set-executionpolicy unrestricted
2) 将文件名保存为ps1
3) 通过以下方法运行(假如文件名是c:a.ps1)
ps c:> .a

示例代码:
function foo ( [int] $x)
{
$x = $x + 1
echo $x
}
foo (1 )
