Help with a For loop and variables
Greetings. I'm completely new to shell scripting and quickly trying to catch on. Here's my scenario:
I have a text file, named ip.txt, containing IP addresses. I want to automatically perform a whois query on each address in the file, search the output for the country, and then put both the IP address and the corresponding country together into a new file.
Here's what I've come up with so far:
Quote:
for i in `cat ./ip.txt`; do whois $i | grep -i 'country:'>>./country.txt; done
The problem with this, obviously, is that it doesn't list the IP address in the output file.
To the best that I can tell, I somehow need to store the grep results as a variable, and then maybe echo both variables into a new file.
Am I on the right track?
In the event that it matters, the system I'm trying to do this on is Debian 6.0.3.
Thanks!

ncc::countrycode
CountryCode(3pm) User Contributed Perl Documentation CountryCode(3pm)
NAME
NCC::CountryCode - Perl extension for blah blah blah
SYNOPSIS
use NCC::CountryCode;
my $cc = new NCC::CountryCode();
my $cc_hash = $cc->getCCs();
print ($cc->isCC('NL')) ? "exists" : "non-existing";
$cc->CC2Country('fr');
$cc->Country2CC('russia');
DESCRIPTION
This module provides class and several methods to simplify mapping between country names and country codes, as they assigned in the
ISO3166.
The CC2Country() method maps country code to the corresponding country name or empty string, if it doesn't exist.
The Country2CC() tries to map passed country name into country code. As the spelling of the name may vary, this function tries to find all
possible matches for passed name. In array context method returns hash of country codes and names, in scalar - a string, containing all
possible country codes and corresponding country names.
The isCC() method verifies, that passed country code is a legal one and returns it in upper case. Otherwise it returns empty string.
The getCCs() method returns the reference to the internal hash, that containes all the country codes with corresponding them country names.
BUGS
In addition to the country codes defined by ISO3166 standart this module also introduce 'UK' as a synonim for 'GB' and 'EU' as additional
'virtual' name for the Europe itself.
