Batch not-equal (inequality) operator

Question

According to this, !==! is the not-equal string operator. Trying it, I get:

C:\\> if \"asdf\" !==! \"fdas\" echo asdf
!==! was unexpected at          


        

Answer 1

Try:

if not "asdf" == "fdas" echo asdf

That works for me on Windows XP (I get the same error as you for the code you posted).
