象運行可執行文件一樣，Powershell運行文件和腳本，也必須使用絕對路徑或者相對路徑，或者要運行的文件必須定義在可受信任的環境變量中。

關于腳本
腳本和批處理都屬于偽可執行文件，它們只是包含了若干命令行解釋器能夠解釋和執行的命令行代碼。

執行批處理文件
批處理是擴展名為”.bat”的文本文件，它可以包含任何cmd控制臺能夠處理的命令。當批處理文件被打開，Cmd控制臺會逐行執行每條命令。那Powershell能夠直接執行批處理嗎？
將下列命令保存為ping.bat

@echo offecho batch File TestpauseDir %windir%/system

然后執行ping
屏幕會打印ping命令幫助，說明調用的ping cmd 而不是ping.bat。
改為：

PS C:/PS> ./pingbatch File TestPress any key to continue . . . Volume in drive C has no label.

這時運行的是批處理。

通過cmd進入cmd控制臺輸入ping發現執行的不是ping命令，而是直接運行ping.bat ，也就是說可以通過.bat 覆蓋cmd命令。這種機制很危險，如果有人侵入電腦，并將系統內部命令篡改成自己批處理，那就太悲劇了。 這種命令與腳本的混淆不會發生在powershell中，因為powershell有更安全的機制。

執行VB腳本文件
將下列命令保存為test.vbs

Set wmi = GetObject("winmgmts:")Set collection = wmi.ExecQuery("select * from Win32_Process")For Each process in collectionWScript.Echo process.getObjectText_Next

執行 ./test.vbs 會遍歷當前Win32進程，并把每個進程的詳細信息通過窗口顯示出來。
怎樣讓VB腳本的通過控制臺輸出呢？
Wscript //H:CScript
怎樣還原VB腳本通過窗口輸出呢？
WScript //H:WScript
在powershell中執行VB腳本
