5. Using the CLI Shell
ROS® v3.11User Guide 98 RMC30
5. Using the CLI Shell
ROS® Command Line Interface (CLI) support enables:
• Execution of commands from a CLI shell.
• Remote execution of commands using RSH or SSH.
• Switching between the CLI shell and the menu system.
Different commands may be available to users at different login session security
levels (guest, operator or administrator).
The ROS® CLI shell may be accessed from a terminal session to the device. A terminal
session may be established in one of three ways:
• Direct cable, via RS-232.
• Remote via RSH.
• Remote via SSH.
When a terminal session is first established to the ROS® device, the user interface presented
will be the full-screen menu interface. Please refer to Section 1.1, “The ROS® User Interface”
for more detail on the menu interface.
The Command Line Interface (CLI) shell may be accessed from any menu by pressing <Ctrl-
S>. Any menu operation in progress, such as changing a configuration parameter, will be
terminated. You may return to the menu system by pressing <Ctrl-S> again or by entering
“exit<CR>” at the shell prompt.
This chapter describes a selection of the most useful commands in detail. For a complete list
of available commands, please refer to Appendix E, Command Line Listing.
