How to open two terminals side by side using `screen`

Question

I use vim a lot. I can open two files side by side with -O option:

$ vim -O hello.{h,cpp}

Today I tried screen:

`C-a |`      => split terminal vertically.
`C-a <tab>`  => switch to the new `region`
`C-a c`      => run bash in this `region`

Can I create two terminals side by side like vim -O with one-line?

Answer 1

If you want this to happen every time you run screen, you can put the following in ~/.screenrc:

vert_split
screen
focus
screen

Otherwise, you can create a new file with these commands, and pass it as a configuration file, eg:

screen -c ~/.splitscreenrc
