Command line interfaces

EVA command line apps

EVA apps are used to configure the system and call controller API functions from the command line or by external scripts. All of the following apps are located in bin folder.

EVA shell

EVA shell (eva-shell, eva -I or eva for single commands) is the primary CLI tool. It allows you to manage local system as well as calling other tools/subshells directly from CLI interactive command line.

With EVA shell you can install updates, backup and restore configuration, start and stop EVA components.

EVA shell provides commands for all EVA ICS API methods, auto completion for everything, command repeating, batch commands and is the recommended way to configure, manage and monitor EVA ICS nodes from command line.
