sorry the browswer not putting code tags around the code when I click on button , so I am adding them manually hope it works.
can someone help me on my sed command please?

I am using sun solaris and Linux , what I want is SED to print any string (or output it to a file preferably) that does not have either "01","03","05","07","10" or "11" on the 9th and 10th position .
e.g from the file below I only want these three lines


Code:
433483433339
167710001710
167730600000


Code:
$cat a.txt
 000000001000
 433483433339 <<< print this since 33 is at 9th and 10th pos
 121121211100 
 167710001710 <<< print this since 17 is at 9th and 10th pos
 167735250310
 167735260510
 167735280710
 167730600000 <<< print this since 00 is at 9th and 10th pos

sed '/^........0[1357]/d;/^........1[01]/d' a.txt

But, I have no experience with openVMS, so I can't say whether or not either of these will work there.


awesome this one worked

how does this command works though .. I understand each parts but how the output of one gets piped to the other?


Code:
sed -e '/^........0[1357]/d' -e '/^........1[01]/d' a.txt

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.
