Update of shares prices without gnucash

[jb]

Hello,

I'm using Gnucash for my personal accounting since several years.
I have recently added stocks accounts.

I would like update, automatically and periodically from my NAS server or from
my firewall machine, share prices values of my stocks. But those machines are a
lite linux distribution without gnucash.

I would like to know if it exists a solution to update  share prices without
using the gnucash -add-price-quotes  command line interface.
For example, maybe, it exists a script which allows to have only perl on the
machine to update the xml file of gnucash with shares prices.

Thanks you for your help.
JeB
