Scripting in Windows using VBScript or Javascript for WSH (Windows Scripting Host) is so convenient. You could write scripts and save them using notepad or any other text-editor as *.vbs or *.js. Double click them and the scripts will be interpreted by cscript.exe or wscript.exe.
To handle the command line parameters, you can use the WScript.Arguments object, the WScript.Arguments.Count gives the number of command line parameters.
' HelloACM.com
If Not IsEmpty(WScript) Then
Dim objArgs
Set objArgs = WScript.Arguments
WScript.Echo "Number of Parameters: " & objArgs.Count
Dim i
For i = 0 To objArgs.Count - 1
WScript.Echo objArgs.Item(i)
Next
objArgs.ShowUsage()
End If
It is interesting to see that ShowUsage of WScript.Arguments will print the name of the current script after text ‘Usage: ‘. The WScript object does not exist in other environment, for example, the web browsers, so we put a Not IsEmpty(WScript) check to ensure code compatibility.
