Custom configuration
By default the config is kept in ~/.screenrc file but using -c option we can pass a custom config
~$ screen -c screen-4regions
Example of a config file:
~$ cat screen-pm # Region 0 screen -t mail1-queue #creates new terminal/prompt select 0 #select window0 stuff "echo Window0^M" #echo a string between quotes, ^M translates to EOL stuff "sshpass -p 'password' ssh -o PubkeyAuthentication=no root@example.com^M" #ssh interactively split #split horizontally split -v #split vertically # Region 1 select 1 focus #get focus on a selected region screen -t mail2-queue #create a new terminal/prompt in the focus window stuff "echo Window1^M" # Region 2 select 2 focus screen -t mail1 stuff "echo Window2^M" split -v # Region 3 select 3 focus screen -t mail2 stuff "echo Window3^M" altscreen on term screen-256color bind ',' prev bind '.' next # #change the hardstatus settings to give an window list at the bottom of the #screen, with the time and date and with the current window highlighted hardstatus alwayslastline #hardstatus string '%{= kG}%-Lw%{= kW}%50> %n%f* %t%{= kG}%+Lw%< %{= kG}%-=%c:%s%{-}' hardstatus string '%{= kG}[ %{G}%H %{g}][%= %{= kw}%?%-Lw%?%{r}(%{W}%n*%f%t%?(%u)%?%{r})%{w}%?%+Lw%?%?%= %{g}][%{B} %m-%d %{W}%c %{g}]'
