A configuração do meu terminador é assim:
[profiles]
[[default]]
# some settings
[[root]]
# some colour settings
use_custom_command = True
custom_command = sudo -i
exit_action = restart
[[lab]]
# some more colour settings
use_custom_command = True
custom_command = ssh -R 2022:localhost:22 lab
exit_action = restart
[[server]]
# some more colour settings
use_custom_command = True
custom_command = ssh server
exit_action = restart
[layouts]
[[default]]
[[[child0]]]
type = Window
order = 0
parent = ""
[[[child1]]]
labels = None, None, None, None
type = Notebook
order = 0
parent = child0
[[[terminal1]]]
profile = root
type = Terminal
order = 0
parent = child1
[[[terminal2]]]
profile = lab
type = Terminal
order = 1
parent = child1
[[[terminal3]]]
profile = server
type = Terminal
order = 2
parent = child1
[[[terminal4]]]
profile = default
type = Terminal
order = 3
parent = child1
Combinando perfis com custom_command
, recebo quatro guias na inicialização, uma com um shell raiz, duas conexões ssh de abertura e uma quarta shell normal.
Essas opções estão documentadas na terminator_config(5)
