Ahmad, the order of the output is not fixed. When I run it using mawk I get:
Code:
2222222222,fghij,09.08.09,948p0
sdjkfh343mn,74895495.89,2222222222,02.05.09,uyiuewy

1111111111,abcde,12.10.09,675069AG

Alternative in shell :
Code:
while read line; do
  if match=$(grep "${line%%,*}" file2); then
    printf "$line\n$match\n"
  fi
done < file1 > file3

Output:
Code:
1111111111,abcde,12.10.09,675069AG
abjkfd689,12.346,1111111111,15.09.09,kjfjlja

Not as efficient as awk though for large numbers but perhaps good enough.

Locale::Codes::LangFam(3pm)				 Perl Programmers Reference Guide			       Locale::Codes::LangFam(3pm)

NAME
Locale::Codes::LangFam - standard codes for language extension identification SYNOPSIS
use Locale::Codes::LangFam; $lext = code2langfam('apa'); # $lext gets 'Apache languages' $code = langfam2code('Apache languages'); # $code gets 'apa' @codes = all_langfam_codes(); @names = all_langfam_names(); DESCRIPTION
The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in ISO 639-5. Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5 language family codes will be used. SUPPORTED CODE SETS
There are several different code sets you can use for identifying language families. A code set may be specified using either a name, or a constant that is automatically exported by this module. For example, the two are equivalent: $lext = code2langfam('apa','alpha'); $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA); The codesets currently supported are: alpha This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages. This is the default code set. ROUTINES
