In
Windows there are some script interpreters
natively available, much more powerful than the
usual dos shell
cmd.
Generally my advice is to use cross platform third
party interpreters like
PHP,
Pyton,
Perl, ...
Bit if you need to do some operations on foreign PCs
without installing anything you can take advantage
of
WSH.
Here are some examples of what you can do, mostly
written in
javascript simply because is much more
better than VBScript.
How to use: ensure
WSH is enabled in your windows
environment, create a text file with the indicated
name, copy the content in it and then run.
- Shutdown the PC:
Shutdows.js(new ActiveXObject("Shell.Application")).ShutdownWindows();
- Prompt for user input:
input.wsf<job id="ComputeInput">
<script language="VBScript">
Function WSHInputBox(Message, Title, Value)
WSHInputBox = InputBox(Message, Title, Value)
End Function
</script>
<script language="JScript">
var sNum = WSHInputBox("Enter a number",WScript.ScriptFullName,"1");
var fNum = parseFloat(sNum);
WScript.Echo(fNum + " x " + fNum + " = " + (fNum*fNum));
</script>
</job>
- Retrieve some system informations:
sysinfo.wsf<job id="SysInfo">
<script language="VBScript">
Function WSHInputBox(Message, Title, Value)
WSHInputBox = InputBox(Message, Title, Value)
End Function
</script>
<script language="JScript">
var oWsh = new ActiveXObject("WScript.Shell");
var oWshSysEnv = oWsh.Environment("SYSTEM");
var oWshPrcEnv = oWsh.Environment("PROCESS");
var oWfs = new ActiveXObject("Scripting.FileSystemObject");
var oWnet = WScript.CreateObject("WScript.Network");
var sMsg = "Data retrived on ";
sMsg += new Date();
sMsg += "\nProcessors: " + oWshSysEnv("NUMBER_OF_PROCESSORS");
sMsg += "\nArchitecture: " + oWshSysEnv("PROCESSOR_ARCHITECTURE");
sMsg += "\nOS: " + oWshSysEnv("OS");
sMsg += "\nDomain = " + oWnet.UserDomain;
sMsg += "\nComputer Name = " + oWnet.ComputerName;
sMsg += "\nUser Name = " + oWnet.UserName;
sMsg += "\n\nWindows folder: " + oWshPrcEnv("SYSTEMROOT");
sMsg += "\nPrograms folder: " + oWshPrcEnv("ProgramFiles");

sMsg += "\nFavorites folder: " + oWsh.SpecialFolders("Favorites");
sMsg += "\nMyDocuments folder: " + oWsh.SpecialFolders("MyDocuments");

sMsg += "\n\nDrives:";
var oDrives = new Enumerator(oWfs.Drives);
for( oDrives.moveFirst(); !oDrives.atEnd(); oDrives.moveNext() )
{
if (oDrives.item().DriveType == 3) sMsg += "\n" + oDrives.item().ShareName;
else if (oDrives.item().IsReady) sMsg += "\n" + oDrives.item().VolumeName + " (" + oDrives.item().FreeSpace/1048576 + " MB free)";
}
var oNetDrives = oWnet.EnumNetworkDrives();
for(var i=0; i<oNetDrives.Count(); i+=2)
{
sMsg += "\nNet drive " + oNetDrives.Item(i) + " = " + oNetDrives.Item(i+1);
}
sMsg += "\n\nPrinter mappings:";
var oPrinters = oWnet.EnumPrinterConnections();
for(var i=0; i<oPrinters.Count(); i+=2)
{
sMsg += "\n" + "Port \'" + oPrinters.Item(i) + "\': " + oPrinters.Item(i+1);
}
WScript.Echo(sMsg);
</script>
</job>
- Iterate through files:
loopfiles.wsf<job id="LoopFiles">
<script language="JScript">
var oWsh = new ActiveXObject("WScript.Shell");
var oWfs = new ActiveXObject("Scripting.FileSystemObject");
var sFld = oWsh.SpecialFolders("Desktop");
if ( !oWfs.FolderExists(sFld) ) throw new Error("No folder?!");
var eFiles = new Enumerator(oWfs.GetFolder(sFld).Files);
var sMsg = "Files contained in \'" + sFld + "\':\n";
for( eFiles.moveFirst(); !eFiles.atEnd(); eFiles.moveNext() )
{
sMsg += eFiles.item().Name + ", ";
}
WScript.Echo(sMsg);
</script>
</job>
- Create and write a text file:
writetxtfile.wsf<job id="CreateTextFile">
<script language="JScript">
var oFs = new ActiveXObject("Scripting.FileSystemObject");
var f = oFs.CreateTextFile("c:\\testfile.txt", true);
f.WriteLine("ciao");
f.Close();
</script>
</job>
