Match complete field
hello,

i have a little problem, i want match the complete field ($1 or $2) with a complete word in another variable.

example:
i have a file with either one or two words per lane:
Code:
 
hsa-mir-4449 
hsa-mir-4707 
hsa-mir-4707* hsa-mir-4707
novelMiR_3551 novelMiR_3563
novelMiR_4330 novelMiR_1963
hsa-mir-625 
novelMiR_3660 hsa-mir-625
hsa-mir-4707* 
hsa-mir-4707 hsa-mir-4707*
novelMiR_440 novelMiR_1963
hsa-mir-470

and want search each word in the file with each line if this word is present.


my try to use match, i.e.
Code:
if (match($1,i) || match($2,i))

with $1,$2 both words per lane and i the complete lane, was not possible, because 'hsa-mir-470' also matches 'hsa-mir-4707'. how can i match only the complete field with complete words in the variable?

can i tell awk that only the complete $1 should match a complete word in i.
something like
Code:
/^$1$/ ~ i

or
Code:
match(\<$1\>,i)

- both not working...

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.
