That is good enough. The loop itself won't cost you any time, at least not compared to opening and reading the file (which is, for a short list, also neglectable).

You might want to think to put the whole mechanism into a function, like this (just a sketch):

Code:
#! /bin/ksh

function pGetCountryDetails
{
typeset f1=""
typeset f2=""
typeset f3=""
typeset f4=""
typeset country_code="$1"

while IFS='|' read -r f1 f2 f3 f4 ; do
     if [ $f3 = $country_code ] ; then
          CountryName=$f1
          CountryRegion=$f2
          CountryCode2=$f4
          return 0
     fi
done < "$input"

return 1
}


# main()

[... get some country_code....]

if ! pGetCountryDetails "$country_code" ; then
     print -u2 - "country code $country_code not found in file"
else
     print - "Country Code is: $country_code"
     print - "CountryName=$CountryName"
     print - "CountryRegion=$CountryRegion"
     print - "CountryCode2=$CountryCode2"
fi
[.... etc. ....]

I hope this helps.

GEOIP_REGION_NAME_BY_CODE(3)						 1					      GEOIP_REGION_NAME_BY_CODE(3)

geoip_region_name_by_code - Returns the region name for some country and region code combo

SYNOPSIS
string geoip_region_name_by_code (string $country_code, string $region_code) DESCRIPTION
The geoip_region_name_by_code(3) function will return the region name corresponding to a country and region code combo. In the United States, the region code corresponds to the two-letter abbreviation of each state. In Canada, the region code corresponds to the two-letter province or territory code as attributed by Canada Post. For the rest of the world, GeoIP uses FIPS 10-4 codes to represent regions. You can check http://www.maxmind.com/app/fips10_4 for a detailed list of FIPS 10-4 codes. This function is always available if using GeoIP Library version 1.4.1 or newer. The data is taken directly from the GeoIP Library and not from any database. PARAMETERS
o $country_code - The two-letter country code (see geoip_country_code_by_name(3)) o $region_code - The two-letter (or digit) region code (see geoip_region_by_name(3)) RETURN VALUES
Returns the region name on success, or FALSE if the country and region code combo cannot be found. EXAMPLES
Example #1 A geoip_region_name_by_code(3) example using region code for US/Canada This will print the region name for country CA (Canada), region QC (Quebec). <?php $region = geoip_region_name_by_code('CA', 'QC'); if ($region) { echo 'Region name for CA/QC is: ' . $region; } ?> The above example will output: Region name for CA/QC is: Quebec Example #2 A geoip_region_name_by_code(3) example using FIPS codes This will print the region name for country JP (Japan), region 01. <?php $region = geoip_region_name_by_code('JP', '01'); if ($region) { echo 'Region name for JP/01 is: ' . $region; } ?> The above example will output: Region name for JP/01 is: Aichi PHP Documentation Group GEOIP_REGION_NAME_BY_CODE(3)
