I think what karaf assumes is that it is something like a shell. So when
you press Ctrl-C in karaf and there is a foreground karaf command like
tail -f running then it is ended. Not sure if this assumption is correct
but as a user it feels right.
Ctrl-D ends the felix framework in the same way as in karaf. Would you
propose to use Ctrl-D differently?

However, Ctrl-C is a specific POSIX terminal code SIGINT which should, by
default, terminate _foreground_ applications (things you invoked in the
shell session).
Meanwhile, in order to be consistent with shells and terminal emulators
across the *nix-verse the proper _exit_ code should be EOF (i.e. Ctrl-D).
I think both of these codes are not properly used in gogo.

While working on documenting the gogo shell better (
https://issues.apache.org/jira/browse/FELIX-5595) I used the current
felix framework distro and tested a lot of the commands.
When I tried the log:tail command using -f to follow changes I noticed a
problematic behaviour. The tail -f command relies on the user pressing
Ctrl-C to interrupt the tail and go back to the shell. In Apache Karaf this
works like expected.
In the felix framework distro pressing Ctrl-C always exists the framework.
So it is impossible to stop a tail -f once you started it.
I opened an issue for this (https://issues.apache.org/jir
a/browse/FELIX-5597) as I think it would be better to have Ctrl-C behave
like in karaf.
I discussed this with Guillaume Nodet on irc and he generally agrees but
he asked me to bring this up on the list as the current behaviour might be
desired.
So what do you think? Should we try to change the behaviour or is it good
and expected that Ctrl-C ends the framework? In the latter case we would
need to have a different solution for ending a tail -f.
