Scopes

Many commands require a "scope" expression to indicate the target on which they operate. Where this is required the usage statements below will use the shorthand nomenclature of <X-scope>.
The various scopes should be replaced on the command line as:

  • <app-scope>
    application <Name|AppID>

  • <entity-scope>
    application <Name|AppID> entity <Name|EntityID>

  • <effector-scope>
    application <Name|AppID> effector <Name>
    application <Name|AppID> entity <Name|EntityID> effector <Name>

  • <config-scope>
    application <Name|AppID> entity <Name|EntityID> config <ConfigID>

  • <activity-scope>
    activity <ActivityID>
    application <Name|AppID> entity <Name|EntityID> activity <ActivityID>

Abbreviations

Many of the commands and scopes have shortened aliases:

activity     act
application  app
entity       ent
policy       pol
