Stackoverflow

What is the point of Stackoverflow? It is full of clues retards with severe platform fanticism. They can't answer any question beyond "how do I add 2+2". Usually they just close harder questions, because they are too stupid to even understand the it. Here I asked a brain dead question about Unix sed behavior, expecting some people actually familiar with Unix to give a clue:

They didn't even got what it is about. I.e. they don't know there are several different sed versions, believing that the broken gnu crap is the light and the way.

If you want posix on Windows, use Cygwin. The sed and awk on it have worked since 1995
