[ILUG] [Possibly OT] Network Traffic Analysis and InterfaceControl

  | eval $'y=$(( ${x//[,\n]/+} ))'  # add, result in $y

 not that it really matters, but I realised overnight the
 `eval' for the version I eventually posted (above) is not
 needed; this is more(?) obvious if re-written as:

         y=$(( ${x//[,$'\n']/+} ))  # add, result in $y

cheers!
