"scr --help" returns nothing even though scr command exist.
Karaf 4.2.0 and 4.3.0-SNAPSHOT
There are several commands with the scope of "scr" but they are not displayed by "scr --help". The commands are displayed by command completer
karaf@root()> scr --help
karaf@root()>
karaf@root()> scr: (Tab pressed to invoke the command completer)
scr:config scr:disable scr:enable scr:info scr:list
Help on a scr command like scr:info produces the following error
karaf@root()> scr:info --help
Error executing command: No component description matching "--help".
karaf@root()>

Is this a bug?
Should I create a Jira?

Re: "scr --help" returns nothing even though scr command exist.
Posted by João Assunção <jo...@exploitsys.com>.
You have two types of commands in Karaf shell: Karaf commands and gogo
commands. Karaf commands provide more bells and whistles than gogo
commands, --help being one of them.
I think scr:<cmd> are gogo commands.
Best regards,
