# screen ## screen One advantage of `screen` is that it is a default package on most Unixy systems. Thus if you logged into a remote server you are more likely to have `screen` available for use than `tmux`. This is why it is worth learning basics of `screen`. ## Splitting * Screen window splitting - * Unlike on `tmux` a shell has to be spawned explicitly after splitting. * To do a vertical split - `Ctrl+a |` then `Ctrl+TAB` to go to the other split. Then as usual, use `Ctrl+a c` to create a window. * For a horizontal split use `Ctrl+a S`.
