3: Command Line Interface
SGX 5150 IoT Device Gateway Command Reference 12
Using Keyboard Shortcuts and CLI
One useful shortcut built into the SGX 5150 IoT device gateway is that the complete text of a
command does not have to be entered to issue a command. Typing just enough characters to
uniquely identify a command, then hitting enter, can be used as a short cut for a command. For
example, at the enable level, "sh" can be used for the "show" command.
Tab Completion is also available using the Tab and Enter keys on the keyboard. Typing the first
few characters of a command, then hitting the Tab key displays the first command that begins with
those characters. Hitting the Tab key again displays the next command that begins with the
original characters typed. You can press Enter to execute the command or you can backspace to
edit any parameters.
The following key combinations are allowed when configuring the gateway using the CLI:

Understanding the CLI Level Hierarchy
The CLI hierarchy is a series of levels. Arranging commands in a hierarchy of levels provides a
way to organize and group similar commands, provide different levels of security, and reduce the
complexity and number commands and options presented to a user at one time.
When you start a command line session, you begin at the login level. This level can be password
protected and provides access to high level status, a few diagnostic commands, and the enable
level. Further gateway information and configuration are accessed via the enable level.
The enable level can also be password protected and is the gateway to full configuration and
management of the intelligent gateway. There are commands for gathering and effecting all
elements of gateway status and configuration, as well as commands that take you to additional
levels. For instance, network specific status and configuration commands are found under the
"configuration" level.
