I have a version of gnu screen that allows vertical splitting with ^A |. I'm trying to pass a vertical split screen command to another window using at.

To do a horizontal split screen at otherwindow split works, but what command do I use for vertical split?

The command is split -v which seems to be un(der)-documented.

Which version added that? Version 4.00.03 on Mac OS X Snow Leopard doesn't support that. It's certainly undocumented on the official GNU site. – Doug Harris Dec 15 '10 at 19:25
@Doug: The only place I've seen it documented is in ^A:help at the bottom left and in the ChangeLog. Apparently it was added in version 4.1. – Dennis Williamson Dec 15 '10 at 19:33
Screen version 4.00.03 (FAU) 23-Oct-06 on Mac OS 10.6.8 supports C-a |, but not 'split -v' – Florenz Kley Nov 23 '12 at 22:01
