Most of the Solaris systems I access through an SSH shell session display a bunch of cruft (e.g., do you have mail?, etc.) when I login. To reduce the amount of chatter, I recently created a .hushlogin file in the home directory of each server I support:
$ touch $HOME/.hushlogin
When this file is present, the logic in /etc/profile will limit what is displayed. Niiiiiice!
