title: Batch not-equal to all text strings
body: <p>When using the batch and comparing two strings and comparing all available choices is done like this 
  if /I %variable%==Something ( 
   echo wuhu
  ) 
  But what i want to do is have a "if not" to all types of one specific string, this should be done like. 
  if not /I %variable%==Something (
   echo Does not work 
  )</p>
  
  <p>But as far as i can see this does not work.
  Is there any way to do it without using for loops in batch? </p>
