Você pode criar um arquivo de configuração de tela personalizado que abrirá várias divisões e lançará seus scripts nelas. Seria algo parecido com isto:
screen script1.sh # Open first screen and launch first script
split # Make second split
focus # Switch to second split
screen script2.sh # Open second screen and launch second script
split # Make third split
focus # Switch to third split
screen script3.sh # Open third screen and launch third script
Coloque isso em um arquivo chamado myscripts e inicie a tela com screen -c myscripts
. Se você preferir divisões verticais, basta adicionar -v aos comandos divididos.
Se você quiser um layout de grade, tente algo assim:
screen script1.sh # Open first screen and launch first script
split -v # Make second split
focus # Switch to second split
screen script2.sh # Open second screen and launch second script
split # Make third split
focus # Switch to third split
screen script3.sh # Open third screen and launch third script
focus # Cycle back to first split
split # Split first split horizontally
focus # Switch to new split
screen script4.sh # Open fourth screen and launch fourth script
