invisible

This is a very simple vbs script that runs a batch script or command without anything appearing on screen. If you put it in a folder and add the folder to you user PATH, you can use it as follows:
>invisible assoc
>invisible echo hello
>invisible <any> <number> <of> <commands> <here>
You can also do:
>"C:\path\to\invisible.vbs" <any> <number> <of> <commands> <here>
Personally I use it this way so I can create shortcuts to batch scripts and run them invisibly, then put the shortcuts somewhere useful like in the "Send to" directory.
