為了解技術思路,研究了一下powershell.
整個開發與部署過程如下:

1.下載WindowsXP-KB926139-v2-x86-ENU

安裝powershell環境;

2.按照代碼要求,寫一個簡單的腳本;

3. 運行powershell時,同 bat是有區別的.注意以下方法:

1) 解除限制:

set-executionpolicy Unrestricted

2) 將文件名保存為ps1
3) 通過以下方法運行(假如文件名是c:a.ps1)
PS C:> .a
[@more@]

示例代碼:

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