Unable to hide welcome screen in Emacs
Add the following to your $HOME/.emacs:
(setq inhibit-startup-screen t)
The next time you start Emacs, the welcome screen shouldn't appear. If you already have Emacs open with the welcome screen, you can kill it with C-x k (Control-x, then k).
(setq inhibit-splash-screen t)
(setq inhibit-startup-message t)
Alternatively you could:
alias emacs='emacs --no-splash'
You can easily do it through emac's menus...
Options -> customize emacs -> top-level customization group
then select environment group, then initialization, and set inhibit startup screen to on.
