Grepping exact pattern and deleting the rows
Hi All,

I have the Input as below:

Code:
21011513    6030    5570    1710       0       0    5140       0    3430    3430       0
21049513  152340  138260  101210       0       0  134440       0   33880   33880       0
31003514   16100   13280    7580    3250    1530   15650    8090    8100    8100       0
31513514   28720   23310   11840    6140    2330   27180   15960   15340   15340       0
16161515    6380    5370    3750     820     530    5950    1790    2200    2200
45141518    7580    6430      40       0     610    6730    3510    6690    6690       0
39019519  152060  130190   92940       0       0  132790       0   39850   39850       0

I want to grep the lines containing 513 and 515 in the positions 6 to 9. and i want to delete those rows. So my output should look like below.

Code:
31003514   16100   13280    7580    3250    1530   15650    8090    8100    8100       0
31513514   28720   23310   11840    6140    2330   27180   15960   15340   15340       0
45141518    7580    6430      40       0     610    6730    3510    6690    6690       0
39019519  152060  130190   92940       0       0  132790       0   39850   39850       0

I have tried the below code:


nawk -F, '$1 !~ /513|515/' sample > op2

With this code i am getting the output as below:

Code:
31003514   16100   13280    7580    3250    1530   15650    8090    8100    8100       0
45141518    7580    6430      40       0     610    6730    3510    6690    6690       0
39019519  152060  130190   92940       0       0  132790       0   39850   39850       0

Since the Row 4 in my Input contains '513' in the positions 3 to 5, that row also getting ignored.

Is there any better way to achieve the desired output ?

Thanks in Advance.

Regards,
am24

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.
