watch in unix lets you watch the output of a command (kinda like 'top' on unix)
it'd be great to be able to do that in karaf too.
then the screen would keep refreshing every second showing the output of the command until the user hit q/enter/ctrl-c or something. So it'd behave a little like unix commands like top/vmstat allowing you on the console to watch things change (e.g. things startup or stop or whatever).
