what does the /c DIR represent in the code below
i know what the %comspec% is but not the rest
what i need to do is run a python file from an HTML page
for a demonstration for collage

Run a DOS Command From an HTML Page
This is achieved by using the Windows Script Host. First, create an instance
of the object WScript.Shell. Then, use its Run method to execute the DOS
command. For example, say your HTML page has a button that will run the DIR
command when clicked. The onclick jscript function would look something like
function btnDIR_onclick()
var WshShell = new ActiveXObject("WScript.Shell");
WshShell.Run("%comspec% /c DIR");
The %comspec% string in the argument for Run() specifies the path and file
name of the command interpreter, Cmd.exe.
