I was trying to figure out how to change the default size of my Gnome Terminal. There isn’t any GUI to change this option (been spoiled by Windoze). After doing some Google searches I found the word I was looking for geometry. Then the ole memory kicked in and I remembered that you can pass in the size to any X Windows application. So I gave it a shot:
gnome-terminal --geometry 80x60
VIOLA! Got what I needed.
