How to open and split multiple files

vim -O app/views/*.erb

This is also from the shell. It will open as vertical splits.

What happens when you do a

:sf app/views/*.erb

from within vim?

Just learned from tonymec@#vim that you can do

:args app/views/*.erb | all

for horizontal splits or

:args app/views/*.erb | vertical all

for vertical.

Not actually from within vim, but perhaps you can run vim like this:

vim -o app/views/*.erb
