> watch in unix lets you watch the output of a command (kinda like 'top' on unix)
> http://en.wikipedia.org/wiki/Watch_(Unix)
> it'd be great to be able to do that in karaf too.
> e.g.
> {code}
> karaf@foo> watch -n 1 --clear "list | grep foo"
> {code}
> 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).
