Help with if then sentence (string in file)
Hello! I'd like some help with a sentance, this 'if' should take a string from the user, then search my list for that string, now only those lines that string is found should be worked on.

I'm new to this, but i'm guessing it's something like this..

Code:
           #!/bin/bash
           OPTIONS="opt1 opt2 opt3"
           select opt in $OPTIONS; do
               if [ "$opt" = "opt1" ]; then
                # how can I search the list for 'opt1' ?
               elif [ "$opt" = "opt2" ]; then
                # or 'opt2' ..
               elif [ "$opt" = "opt3" ]; then
                # or 'opt3' ..
               else
                clear
                echo bad option
               fi
           done

Maybe there's something better than an if sentance for this?
The file is a list of countrys and citys, like this:

Code:
Country: Sweden, City: Stockholm
Country: Sweden, City: Malmö
Country: Norway, City: Oslo
Country: Norway, City: Bergen

Let's call this file 'addresses' and, the options in the script could be country names, like Sweden or Norway, and if the user choses 'Norway' we would copy all 'addresses' with Norway, as Country

I hope you understand, and can find some time to help me! (and please, if you have a solution, try and explain it alittle, as I said, i'm new.. )

ip::country::maxmind

IP::Country::MaxMind(3) 				User Contributed Perl Documentation				   IP::Country::MaxMind(3)

NAME

       IP::Country::MaxMind - Look up country by IP Address

SYNOPSIS

	 use IP::Country::MaxMind;

	 my $gi = IP::Country::MaxMind->new(GEOIP_STANDARD);

	 # look up IP address '65.15.30.247'
	 # returns undef if country is unallocated, or not defined in our database
	 my $cc1 = $gi->inet_atocc('65.15.30.247');
	 my $cc2 = $gi->inet_atocc('yahoo.com');

DESCRIPTION

       This module adapts the Geo::IP module to use the same interface as the IP::Country modules; thus allowing users to easily switch between
       using the two underlying databases.

DATABASE UPDATES

       Free monthly updates to the database are available from

	 http://www.maxmind.com/download/geoip/database/

       If you require greater accuracy, MaxMind offers a Premium database on a paid subscription basis.

       The author of this module is in no way associated with MaxMind.

CLASS METHODS

       $gi = IP::Country::MaxMind->new( $flags );
	   Constructs a new IP::Country::MaxMind object with the default database located inside your system's datadir, typically
	   /usr/local/share/GeoIP/GeoIP.dat.

	   Flags can be set to either GEOIP_STANDARD, or for faster performance (at a cost of using more memory), GEOIP_MEMORY_CACHE.  When using
	   memory cache you can force a reload if the file is updated by setting GEOIP_CHECK_CACHE.

       $gi = IP::Country::MaxMind->open( $database_filename, $flags );
	   Constructs a new Geo::IP object with the database located at $database_filename.

OBJECT METHODS

       All object methods are designed to be used in an object-oriented fashion.

	 $result = $object->foo_method($bar,$baz);

       Using the module in a procedural fashion (without the arrow syntax) won't work.

       $cc = $gi->inet_atocc(HOSTNAME)
	   Takes a string giving the name of a host, and translates that to an two-letter country code. Takes arguments of both the 'rtfm.mit.edu'
	   type and '18.181.0.24'. If the host name cannot be resolved, returns undef.	If the resolved IP address is not contained within the
	   database, returns undef.

       $cc = $gi->inet_ntocc(IP_ADDRESS)
	   Takes a string (an opaque string as returned by Socket::inet_aton()) and translates it into a two-letter country code. If the IP
	   address is not contained within the database, returns undef.

       $cc = $gi->db_time()
	   Returns zero. For compatibility only.
