"driver":
cat example | sed -e 's/\(.*\)driver *\([^ ]*\) \(.*\)/\2/'

Subject: Re: grep for line.
While I don't know the answer (I stopped using awk years ago), I may
understand the question a bit better. As I read the original poster's
messages, he wants to do the following:
1. Find one or more lines in a file (or set of files) that contains a
specific string. This, as we've all been noting, is a conventional
problem
for grep.
2. Examine the output of grep to find a string that is in an
*unpredictable*
location in each of the lines.
awk can probably do the second, and I'm sure someone on the list can
explain
how (not me; I use perl for this sort of thing), but Richard's answer
relies
on the target string being in a known position. To extend his examp,e
it's
as though you needed to find the word following SSC/ESCC in the following
2
lines:
The SCC/ESCC driver can support any mix of SCC and ESCC chips
The revised SCC/ESCC driver is also able to support any mix of SCC and
ESCC
chips
Or imagine a set of lines all about the same topoc, each with a number in
an
unknown location. How would one find all the numbers?
One or the other of these is, I think, roughly what the poster wants to
achieve.
