[lcd4linux] Display Script output

[Gabi M. <za...@ya...>]

Hi,

I am trying to display the output of a script shows the hows current download and upload speeds for a network interface by calculating the difference between current transmitted or received bytes and their values one second ago.
How can I run the script just once and send the output to the lcd screen? I can't use exec plugin as it needs to have an interval too. 

Thank you !
Gabi
