> It would be great if forge has a watch command out of the box, you can use to keep running another command.
> The use case is to run a command that maybe display some runtime data or something. And then you want that to be displayed in real time.
> We have this command in Apache Karaf. Here is the options it provides which can be of inspiration
> {code}
> karaf at root> watch --help
> DESCRIPTION
>         shell:watch
> 	Watches & refreshes the output of a command
> SYNTAX
>         shell:watch [options] command
> ARGUMENTS
>         command
>                 The command to watch / refresh
> OPTIONS
>         -a, --append
>                 The output should be appended but not clear the console
>         --help
>                 Display this help message
>         -n, --interval
>                 The interval between executions of the command in seconds
>                 (defaults to 1)
> {code}
> The trick is that the console should be cleared.
> Use cases can also be for watching your servers where you have a plugin that has some commands to gather details. Then you can use watch to update the data in real time.
