Grep? - using a file of terms to search another file when the information is on a different line
I have a flat file that looks like this, let's call it Chromosome_9.txt:
Code:
FT                   /Gene_Name="Guanyl-Acetylase 9"
FT                   /Gene_Number"36952"
FT                   /Gene_Name="Endoplasmic Luciferase"
FT                   /Gene_Number"36953"
FT                   /Gene_Name="Variant Antigen Protein 12"
FT                   /Gene_Number"36954"
FT                   /Gene_Name="Acyl-CoA Synthetase 11"
FT                   /Gene_Number"36955"
FT                   /Gene_Name="Conserved protein, unknown function"
FT                   /Gene_Number"36956"

This is a file in a specialized format that contains all the information about genes on a chromosome, including the names and associated numbers. What I have is a list of numbers ("/Gene_Number," above), like this, let's call it gene_names.txt:
Code:
2568
3658
9567
23657
63654
76532

but I need the names associated with those numbers (on the line above the number in the file). This would be trivial is they were on the same line because then I could use:
Code:
grep -f gene_names.txt Chromosome_9.txt

Because the search term and the actual information I am looking for are on different lines, I am not sure what to do.

Thanks!

locale::language

Locale::Language(3perl) 				 Perl Programmers Reference Guide				   Locale::Language(3perl)

NAME

       Locale::Language - standard codes for language identification

SYNOPSIS

	  use Locale::Language;

	  $lang = code2language('en');	      # $lang gets 'English'
	  $code = language2code('French');    # $code gets 'fr'

	  @codes   = all_language_codes();
	  @names   = all_language_names();

DESCRIPTION

       The "Locale::Language" module provides access to standard codes used for identifying languages, such as those as defined in ISO 639.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639 two-
       letter codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying languages. The ones currently supported are:

       alpha-2
	   This is the set of two-letter (lowercase) codes from ISO 639, such as 'he' for Hebrew.

	   This code set is identified with the symbol "LOCALE_LANG_ALPHA_2".

	   This is the default code set.

       alpha-3
	   This is the set of three-letter (lowercase) bibliographic codes from ISO 639, such as 'heb' for Hebrew.

	   This code set is identified with the symbol "LOCALE_LANG_ALPHA_3".

       term
	   This is the set of three-letter (lowercase) terminologic codes from ISO 639.

	   This code set is identified with the symbol "LOCALE_LANG_TERM".

ROUTINES

       code2language ( CODE [,CODESET] )
       language2code ( NAME [,CODESET] )
       language_code2code ( CODE ,CODESET ,CODESET2 )
       all_language_codes ( [CODESET] )
       all_language_names ( [CODESET] )
       Locale::Language::rename_language  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Language::add_language  ( CODE ,NAME [,CODESET] )
       Locale::Language::delete_language  ( CODE [,CODESET] )
       Locale::Language::add_language_alias  ( NAME ,NEW_NAME )
       Locale::Language::delete_language_alias	( NAME )
       Locale::Language::rename_language_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Language::add_language_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Language::delete_language_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes man page.
