It seems like there's a slightly simpler method... Since the default FS for awk is whitespace, and the sample sentences appear to only use single-spacing (and hence the number of fields is one greater than the number of spaces), we can simply do:
Code:
echo "How many spaces?" | awk '{print "That sentence has "(NF -1)" spaces"}'

Or not?

Code:
echo "$answer"|awk -F "[ ]" '{print NF-1}'

@treesloth. I missed you post as it was on a new page. I came up with the same thing but modified the field separator to use every individual space.

Odd. Nobody mentioned the wc utility at all.

It was mentioned by the OP to count characters and words. How would you use wc to count blank spaces?

The NR-1 solution only works if there is one space between words. Smilie Mine counts all spaces...

Not if you use "[ ]" as a field separator as I suggested then it does count all the spaces. Just give it a try.
