PowerShell时间记录脚本_PowerShell

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
[@more@]

示例代码:

function foo ( [int] $x)
{
$x = $x + 1
echo $x
}
foo (1 )
