[Gnuplot-info] How to disable gnuplot startup message?

[Youjun H. <yj...@gm...>]

Hi, all

 I'm using gnuplot interactively.   Everytime I type `gnuplot` in my
termial, a message such as follows  appears

    G N U P L O T
    Version 4.2 patchlevel 3

After seeing this message many times, I think I remember it well and want to
disable this startup message.
Is it possible to disable this startup message?
Thanks for your help and appologize for the same question being asked a
several times.
