Warning
Follow the commands in this guide with guidance from a Linewize Support Engineer.
School Manager has a two-part Command Line Interface (CLI): SphireOS (a proprietary product of Linewize) and Bash. You may be familiar with Bash if you have used a Linux terminal. However, the implementation of Bash for School Manager is limited, with most standard Linux/Unix utilities removed.
Accessing the CLI
Access to the CLI is local only and requires you to connect to the appliance with a keyboard and mouse. Alternatively, SSH access is available to School Manager, provided it has been preconfigured via the cloud interface in Advanced Configuration.
- On boot, the School Manager will provide a login prompt to the SphireOS CLI.
- Press Enter to log in.
- If you want to get straight to Bash, type system debug exec bash to switch across.
- From Bash, type exit to switch back to SphireOS.
Warning
School Manager may get stuck in a start-up check mode if cloud connectivity is unavailable, where it will reboot every few minutes to establish a connection. If the device is in this state, you can break out of the start-up checks by entering Ctrl + Alt + Delete.
