Redirect to a Variable? Or is it cmd cap?

Hi,

Im reading an ANSI text file and greping for a pattern. Then i cut what i dont need from that pattern. So now i just have what i need. What i have now just so happens to be a constant integer. How can i save this integer in a varaible? Or do i use command capture in some form?

Code:
cat Hello.txt | egrep "That One Pattern" | awk '{print $NF}'

Also..This command might be really useful to me, i just dont understand it.
Since maybe i can use these varaibles with the one i would like to store above..

Code:
awk '{for (i=1; i<=NF; i++) s=s+$i}; END{print s}'

NAME
Mail::SPF::Mod::Redirect - SPF record "redirect" modifier class DESCRIPTION
An object of class Mail::SPF::Mod::Redirect represents an SPF record modifier of type "redirect". Constructors The following constructors are provided: new(%options): returns Mail::SPF::Mod::Redirect Creates a new SPF record "redirect" modifier object. %options is a list of key/value pairs representing any of the following options: domain_spec See "new" in Mail::SPF::Mod. new_from_string($text, %options): returns Mail::SPF::Mod::Redirect; throws Mail::SPF::ENothingToParse, Mail::SPF::EInvalidMod Creates a new SPF record "redirect" modifier object by parsing the string and any options given. Class methods The following class methods are provided: name: returns string Returns 'redirect'. name_pattern: returns Regexp Returns a regular expression that matches a modifier name of 'redirect'. precedence: returns real Returns a precedence value of 0.8. See "precedence" in Mail::SPF::Mod. Instance methods The following instance methods are provided: params See "params" in Mail::SPF::Mod. domain_spec: returns Mail::SPF::MacroString Returns the "domain-spec" parameter of the modifier. process($server, $request, $result): throws Mail::SPF::Result If no mechanism matched during the evaluation of the current SPF record, performs a recursive SPF check using the given SPF server and request objects and substituting the modifier's target domain name for the request's authority domain. The result of the recursive SPF check is then thrown as the result of the current record's evaluation. However, if the target domain has no acceptable SPF record, a "permerror" result is thrown. See RFC 4408, 6.1, for details. See Mail::SPF::Mod for other supported instance methods. SEE ALSO
