Hi all,
I would like to ask:
In a running process in linux, sometimes we will quit or stop it by interrup signal like "^Z","^C", i would like to as which deamon is responsible for signal handling?

I would like to build a cramfs /jffs2 rootdisk with signal as above, is it possible and how can i do it?

Thanks
Alice

Well, the kernel handles the initial keyboard interrupt and the delivering of the signal. Most of the time the shell decides what to do with it, unless the individual program decides to catch it.
