Using Command-Line Parameters in Scripts
A command-line parameter is a bit of text specified after the filename of a script when it is executed from a command prompt (see the following examples). The function to convert a single command-line parameter into a variable is the following:
Function CommandLine(Number) Set Arguments = WScript.Arguments If Number <= Arguments.Count Then CommandLine = Arguments(Number - 1) Else CommandLine = "" End If End Function
For example, to display the second command-line parameter passed to a script, issue the following statement:
Although the command line may seem to be an antiquated concept,
it’s still very much a part of Windows. When you double-click
.vbs file, for example, Windows actually
executes the following command:
filename.vbs (the file that was
double-clicked) is the command-line parameter for
wscript.exe, telling it which script to run.
Scripts also accept command-line parameters, which is accomplished
wscript.exe filename.vbs param1 param2
The two additional parameters,
param2, are both passed to the script as
command-line parameters when it is run.
The problem with providing command-line arguments to your script is that Windows considers scripts to be documents instead of executables.
