Ioannis Canellos commented on KARAF-1382:
-----------------------------------------
Well, you usually need to use pipes when you want to pass the output of a
command to an other command, so I don't think that in the case you describe
pipes are of any use.
Now regarding your script. Even if you just execute commands sequentially there
is a good chance that the cellar commands will not be available right after the
feature installation. Will require the registration of services etc. So you
will have to either wait for a while or wait on service.

> Project: Karaf
> Issue Type: Bug
> Components: karaf-shell
> Affects Versions: 2.2.6
> Environment: W7 x64
> Reporter: Pavel Vasilchenko
>
> I trying create karaf script for starting Cellar like this:
> tesb:start-cluster = { features:install cellar | cluster:group-create $args |
> cluster:group-set $args} ;
> But when I execute this command I get exception at command
> cluster:group-create because, if I right understand, Karaf invoke pipes as
> parallel commands.

> And in this case Karaf tries to run command cluster:group-create before
> cellar is successfully installed.
> How can I run cluster:group-create in Karaf after Cellar feature will be
> successfully installed?
