School Manager Command Line Interface

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 the majority of 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 in Advanced Configuration via the cloud interface.

  1. On boot, the School Manager will provide a login prompt to the SphireOS CLI. 
  2. Press Enter to log in. 
  3. If you want to get straight to Bash, type system debug exec bash to switch across. 
  4. 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 not available, 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.
