Using sed to insert at position x and then every interval y for each line
Thanks to help from Don Cragun in post 302924174, I'm off and getting into trouble on my own (finally) with sed.

Here is my goal - insert
Code:
\\r\n

at the 60th character on each line and then every 76th character thereafter:

Input:
Code:
6F,00,72,00,20,00,73,00,69,00,74,00,20,00,61,00,6D,00,65,00,74,00,2C,00,20,00,63,00,6F,00,6E,00,73,00,65,00,63,00,74,00,65,00,74,00,75,00,72,00,2E,00,22,00,00,00;
22,00,54,00,68,00,65,00,20,00,71,00,75,00,69,00,63,00,6B,00,20,00,62,00,72,00,6F,00,77,00,6E,00,20,00,66,00,6F,00,78,00,5C,00,20,00,63,00,6F,00,6E,00,73,00,65,00,63,00,74,00,65,00,74,00,75,00,72,00,2E,00,22,00,00,00;

Output:
Code:
6F,00,72,00,20,00,73,00,69,00,74,00,20,00,61,00,6D,00,65,00,\
74,00,2C,00,20,00,63,00,6F,00,6E,00,73,00,65,00,63,00,74,00,65,00,74,00,75,\
00,72,00,2E,00,22,00,00,00;
22,00,54,00,68,00,65,00,20,00,71,00,75,00,69,00,63,00,6B,00,\
20,00,62,00,72,00,6F,00,77,00,6E,00,20,00,66,00,6F,00,78,00,5C,00,20,00,63,\
00,6F,00,6E,00,73,00,65,00,63,00,74,00,65,00,74,00,75,00,72,00,2E,00,22,00,\
00,00;

So I tried:
Code:
sed 's/./&\\\r\n/60 s/./&\\\r\n/76' input

but get a syntax error for char 16 being an unknown option to 's'.

This is puzzling to me as I'm able to successfully insert each 60 characters of every line with:
Code:
sed 's/./&\\\r\n/60' input

Shouldn't latter throw the same error?

Kind regads,

gus

locale::codes::langext

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

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.
