The simple answer to the elliptically stated problem is:
MyVal = 'word3'
A more general solution, using regex is:
556 $ echo 'word1 word2 9.12 word3.ext' | sed 's/.* \([^.]*\).*/\1/'
word3
557 $
This finds the last substring in the subject preceded by a space
and followed by a period.
Full disclosure, for Tony to gloat:
o It's easier to code than to review.
o I got it right on the third try.
o I haven't fuzz tested.
