Get started with the RobustOS CLI

Learn how to access the RobustOS command-line interface (CLI), find command help and run your first read-only command.

Overview

The RobustOS CLI lets you view device information, check operating status and perform supported management tasks using text commands. Available commands and access options can vary by device and firmware.

Access: Local SSH and remote access through Robustel Cloud Manager Service (RCMS). Required account role: Admin.

Before you begin

A RobustOS device with the relevant access method available and an Admin account authorized to access it.
For SSH: an SSH client, a network path to the device and its management IP address.
For RCMS: a connected device and the required remote CLI permissions.

Access the CLI

Option 1: Connect through SSH

Open a terminal on your computer.
Connect using your account and device address:
```
ssh <username>@<device-ip>
```
Replace the placeholders with your own values. For example:
```
ssh admin@192.168.0.1
```
If prompted, verify the host-key fingerprint through a trusted channel before accepting it.
Enter the account password. The CLI prompt appears after successful sign-in.

Important: The address in the example is illustrative. Use the actual management address of your device.

Option 2: Access the CLI through RCMS

Use the remote CLI function for the connected device in RCMS. See RCMS CLI access for the remote procedure (registration required).

Understand the command prompt

The prompt indicates that the device is ready for a command. The following prompt was observed on an R5030:

Enter the command itself, without the prompt. Your prompt may differ. After entering a command, wait for its output and the prompt to return before entering the next command. Some queries take longer than others.

Get command help

At the CLI prompt, type ? to list available commands. On the tested CLI, help appears without pressing Enter. To inspect a group, type its name followed by a space and ?:

status ?

The following is an excerpt of the root command list returned by an R5030; the remaining entries are omitted:

# ?
  !                       Comments
  add                     Add a list entry of configuration
  add_preferred           smart roaming add preferred plmn list
  clear                   Clear statistics
  ...

Enter help for an overview of CLI help and completion keys. Press Ctrl-U to clear the current input without executing it. Enter may complete, check and execute the current command. Use the syntax shown by your device.

Run your first command

1. Enter the command

At the device CLI prompt, enter:

ver

2. Review the output

The device displays its firmware version. This example was observed on an R5030:

Version 5.6.0 (6ded0c7)
Apr 30 2026 16:41:19

Your version and build date may differ.

For more device information, enter status system. Remove sensitive device identifiers before sharing the output.

Troubleshooting

I cannot connect

Check the network connection and device management address.
Verify that the relevant SSH or RCMS remote access service is available.

Login fails

Check the account name and password, and confirm that the account is authorized for CLI access.

A command is not recognized

Check its spelling and use ? to inspect options available on your model and firmware.

End the session

Enter exit to leave the CLI and close the SSH session.
