colsanders87

Hello,
I am trying to name a txt file with the output of this command:

wmic csproduct get identifyingnumber >> c:users%username%desktop([b]S.T.#Here[/b][italic][/italic][color=Red][/color]).txt

which displays the Service tag number of machines and writes the service tag number into this text file. I have been beating my head in on this one, please help me.
