how can i isolate the random sequence of numbers using awk?
as you can see there is a delimiter after c8 "::". Awk sees the rest as fields because it doesn't recognize spaces and tabs as delimiters. So i am basically looking to isolate 20030003ba13f6cc. Can anyone help?

c8::20030003ba13f6cc disk connected configured unknown

Here is a sed command to do it all:
Code:
$ echo "c8::20030003ba13f6cc disk connected configured unknown
> f9::8808080809 useless junk" |sed -n '/disk/s/[^:]*::\([^ ]*\) .*$/\1/p'
20030003ba13f6cc
$
