Subject: script question
Is there a way to display the number of fields in a
string using the awk command? Suppose I have a string
like this:
string="hi there, steve, how are you"
I want to be able to count the number of fields in
this string as delimited by the ','. It looks like I
want to do something like this:
echo $string | awk -F, '{print $NR}'
This should return 3, but it just returns 1. Can
anyone help me out here?
Thanks!
-Stephen Spalding
