overwriting shell:logout and ^D for Karaf console?
For running Karaf in the foreground, is there a way I
can "overwrite" the shell:logout Karaf command so I can insert
additional logic guarding the actual logout?
Can I disable shell:logout completely?
(I already have my own quit command which could do all I want.)
How could I do the same for preventing a user from existing Karaf via Control-D?
Thanks!

Yes, an option for disabling Ctrl-D would be great.
Perhaps when running Karaf in the foreground this could be the default (as a 'logout' is equal to 'shutdown').

FYI,
I created https://issues.apache.org/jira/browse/KARAF-6321
about that.

Hi Max,
Understood, I see the points, I will add some options to allows you to
deal with CTRL-D and logout (probably via etc/org.apache.karaf.shell.cfg
configuration).

To give more context: In my Karaf I have potentially very long running "background jobs".
I want to avoid that the user (which is a developer) terminates a foreground Karaf and indirectly aborts these jobs by accident.
If I had the option of programmatically intercepting ctrl-d, I could ask the user "are you sure to exit?"
A 2nd best solution for me would be to disable ctrl-d completely.
I already implemented my own "q(uit)" Karaf command, so my command can safeguard the termination.
But then I would like to disable also the regular shell:logout command.
To be back at my original question :-)

-Max

Hi,
You want to fully disable CTRL-D ? (and force "logout" usage instead)
I can add an option to ssh for that.

I'm also interested to know how one can disable the Ctrl-D logout behaviour?

Let me simplify my question: Is there a way to disable a command like "shell:logout"?
