▀ Command Line Interface

Command Line Interface

The CLI is a multi-threaded man machine interface that allows users to manipulate, configure, control, and query the

various components that make up the system and the services hosted within the system. The CLI contains numerous

command sets that perform various pre-defined functions when entered by a user. The CLI communicates with other

controls and software tasks that make up the operating system.

The CLI provides numerous features, including:

Simultaneous multiple CLI user support, providing a CLI instance for every context.

The maximum number of multiple CLI session support is based on the amount of available memory. The

Resource Manager, however, reserves enough resources so that the following minimum number of CLI

sessions are assured:

Local or remote management login support

Hierarchical structure supporting two command modes

Differentiated administrative user privileges

Intuitive CLI command prompt displaying user's exact location within the CLI, command mode, and user

privilege level

CLI command auto-completion feature that allows users to enter only enough characters to make a command

unique, prompting the system to complete the rest of the command or keyword by pressing the <Tab> key

CLI auto-pagination, improving the readability of command output displays

Complete command history features, allowing users to review all commands previously entered during current

session, and EMACS-style command line manipulation features increasing CLI usability
