I need some logic to work out a value for me - this value is _always_ the 3rd last field in a string seperated by '.' but the string could be 5 or 6 fields long, e.g

foo.bar.VALUE.baz.lala

foor.bar.gigi.VALUE.baz.lala

I need to find VALUE - if this were python or something i could do it but this has to be in shell -

Any clues?

thanks
