The ABLE command line interface (CLI) provides the primary method for interacting with ABLE. The command line is sometimes referred to by the UNIX® naming as a shell. The ABLE shell is a very basic UNIX® bourne shell and should be familiar to anyone experienced with that environment.

The CLI is a flexible environment and commands can be placed in a script file for automation purposes. All the current commands are documented in Part II, “Command Reference”.
