Using the Shell to Perform the Update
Although Sourcefire recommends that you use the web interface on your 
Defense Centers to perform updates, there may be rare situations where you 
need to update the appliance using the bash shell.
IMPORTANT!
Do not use the shell to update a fresh, unconfigured (Version 5.2) 
installation of the Sourcefire 3D System. Before you update an appliance using 
the shell, make sure that you complete its initial setup using its web interface. 
For the Version 5.2.0.5 update, managed devices reboot. Managed devices do 
not perform traffic inspection, switching, routing, NAT, VPN, or related functions 
during the update. Depending on how your devices are configured and deployed, 
the update process may also affect traffic flow and link state. For more

To install the update using the shell:
