Sorry for misanderstanding. My question was about a vbs script. I found this example:
'*******************************************************************************
'Name.............: Del_SMS_record.vbs
'Date.............: 04/05/02
'Author...........: Manohar Mathan
'Function.........: Deletes resource from Site Server
'Usage............: cscript Del_SMS_record.vbs computername
' OR
' Double click on script, it will prompt you for COmputerName
' Can be used in a 'FOR' statement to delete multiple computers.
'
