Merging multiple files from multiple columns
Hi guys,
I have very basic linux experience so I need some help with a problem.
I have 3 files from which I want to extract columns based on common fields between them.

File1:
Code:
--- rs74078040 NA 51288690 T G 461652 0.99223 0.53611 3
--- rs77209296 NA 51303525 T G 461843 0.98973 0.60837 3
--- rs7985170 NA 51304203 C T 461852 0.99215 0.541 3

File2:
Code:
id rsid chromosome pos allele_A allele_B index average_call info
--- rs74078040 NA 51288690 T G 461652 0.99852 0.52725 2
--- rs77209296 NA 51303525 T G 461843 0.99992 0.90562 2
--- rs7985170 NA 51304203 C T 461852 0.99994 0.93283 2
--- rs145780716 NA 19032912 G A 2054321 0.9988 0.026123 2

File3:
id rsid chromosome pos allele_A allele_B index average_call info
Code:
--- rs74078040 NA 51288690 T G 461652 0.956 0.8558 1
--- rs77209296 NA 51303525 T G 461843 0.9843 0.8989 1
--- rs7985170 NA 51304203 C T 461852 0.9323 0.6754 1
--- rs145780716 NA 19032912 G A 2054321 0.9098 0.7632 1

I want to take all the rows from File1 and say columns 1-7 (which are the same in all the files) and then add column 8 from File 2 and columns 9 and 10 from File3.
Note that File1 doesn't have a header but the other files do. Also, File1 has less lines than the other files which have the same number of lines.

The output would look like:
Code:
--- rs74078040 NA 51288690 T G 461652 0.99852 0.8558 1
--- rs77209296 NA 51303525 T G 461843 0.99992 0.8989 1
--- rs7985170 NA 51304203 C T 461852 0.99994 0.6754 1

Any help would be greatly appreciated.
Thanks!

locale::codes::langext

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

NAME

       Locale::Codes::LangExt - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangExt;

	  $lext = code2langext('acm');		       # $lext gets 'Mesopotamian Arabic'
	  $code = langext2code('Mesopotamian Arabic'); # $code gets 'acm'

	  @codes   = all_langext_codes();
	  @names   = all_langext_names();

DESCRIPTION

       The "Locale::Codes::LangExt" module provides access to standard codes used for identifying language extensions, such as those as defined in
       the IANA language registry.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language
       registry codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language extensions. 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 = code2langext('acm','alpha');
	  $lext = code2langext('acm',LOCALE_LANGEXT_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from the IANA language registry, such as 'acm' for Mesopotamian Arabic.

	   This is the default code set.

ROUTINES

       code2langext ( CODE [,CODESET] )
       langext2code ( NAME [,CODESET] )
       langext_code2code ( CODE ,CODESET ,CODESET2 )
       all_langext_codes ( [CODESET] )
       all_langext_names ( [CODESET] )
       Locale::Codes::LangExt::rename_langext  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangExt::add_langext  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangExt::delete_langext  ( CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangExt::delete_langext_alias  ( NAME )
       Locale::Codes::LangExt::rename_langext_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::delete_langext_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
