C'mon Gurus...

All I want is to look for the pattern in the file...If I found it at 5 places... all I want to do is print lines after those pattern(line) until I fond a blank line.

Code:
Log EXAMPLE :


MT:Exception caught 
The following Numbers were affected:
1234
2345
2346

Error
java.lang.InternalError: Can't connect to X11 
      Exception caught 

The following numbers were affected:
11111
22222
33333
44444
55555

java.lang.InternalError: Can't connect to

This is the command I used

Code:
nawk 'c-->0;$0~s{if(b)for(c=b+1;c>1;c--)print r[(NR-c+1)%b];print;c=a}b{r[NR%b]=$0}' b=0 a=10 s="The following numbers were affected:" Process.log


Above command gives me 10 lines after the serach string.

But I just want the 3 and 5 lines in this case. I want to break the print if it hits the blank line.

locale::codes::language

Locale::Codes::Language(3)				User Contributed Perl Documentation				Locale::Codes::Language(3)

NAME

       Locale::Codes::Language - standard codes for language identification

SYNOPSIS

	  use Locale::Codes::Language;

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

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

DESCRIPTION

       The "Locale::Codes::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. 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:

	  $lang = code2language('en','alpha-2');
	  $lang = code2language('en',LOCALE_LANG_ALPHA_2);

       The codesets currently supported are:

       alpha-2, LOCALE_LANG_ALPHA_2
	   This is the set of two-letter (lowercase) codes from ISO 639-1, such as 'he' for Hebrew.  It also includes additions to this set
	   included in the IANA language registry.

	   This is the default code set.

       alpha-3, LOCALE_LANG_ALPHA_3
	   This is the set of three-letter (lowercase) bibliographic codes from ISO 639-2 and 639-5, such as 'heb' for Hebrew.	It also includes
	   additions to this set included in the IANA language registry.

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

ROUTINES

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