Ralph,

Try sed -n -E -e '1s/^.*[^A-Za-z0-9_-]?([0-9]+[.][0-9]+[.][0-9]+)[^A-Za-z0-9_-]?.*$/\1/p' (or its equivalent in Perl).

-n = Don't print out lines that do not match the pattern
-E = Telsl sed to recognize +
pattern = <digits>.<digits>.<digits> (no attempt to rule out nonsense like 0.0.0)

To match Ralph's sample failure:

> savaii:~ baker$ echo "flex 2.5.35 Apple(flex-31)" | sed -n -E -e '1s/^.*[^A-Za-z0-9_-]?([0-9]+[.][0-9]+[.][0-9]+)[^A-Za-z0-9_-]?.*$/\1/p'
> 2.5.35
