Actually, it acts on the currently select()d filehandle, which is generally STDOUT, but not always. That's why you still sometimes see the convoluted select((select(STDOUT),$|=1)[0]);

    I know, I already said that. I wasn't making a general statement, I was talking about the variables in his program (STDOUT and FILE).

    And that convoluted bit? That's how autoflush does it too. (Well, a slightly safer variation.) I prefer to use autoflush cause it's way more readable.

      >I know, I already said that

      Aye. 5 minutes before I did (so please excuse the lag, it took me awhile to find the correct incantation), and in a different node :-P. The statement "$| = 1; only affects STDOUT, not FILE" doesn;t convey an understanding of this though, which was I mentioned it.

        Oops, sorry, there was a much longer period between the time I wrote and the time I noticed your post.
