I have a Linux server with services running inside systemd
containers. To access the shell inside a container, I can use the command machinectl login <container>
. That command will give me the container's login prompt and this message:
Connected to container <name>. Press ^] three times within 1s to exit session.
After I'm done and type exit
or logout
, I'm returned to the container's login prompt. In order to get back to the host's shell, I need to send the control character ^]
(three times within one second).
I'm using an international (Finnish) keyboard and instead of having its own dedicated key, the ]
character is ⌥+9. But when I press ctrl+⌥+9, it's not recognized as the control character ^]
and I'm stuck at the login prompt.
How can I send a proper ^]
control character with an international keyboard?
