How to replace symbols by position using SED
Hi all,

I need your help.

For example I have string in file.txt:
-x -a /tmp/dbarchive_NSS_20081204 -f 900 -l 1 2008/12/04 2008/12/04

So, I need to replace symbols from (for e.g.) position 26 till 33 with symbols which I have in file replace.txt

And I have no idea how to do it.
If anybody can help me I will be very appreciative

Thanks in advance,
Best Regards,
Roman

re

RE(1)							      General Commands Manual							     RE(1)

NAME

       re - programm to conver russian texts between different encodings

SYNOPSIS

       re <infile><outfile><infrmt><outfrmt><f|b|s><u|l|s>

DESCRIPTION

       This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page.

       re is a program that converts russian texts between encodings.

OPTIONS

       The easiest way to convert some file into readable form (KOI-8), just type this:

       re <SourceFile> <DestFile> ? K

       where :

       <SourceFile> - unreadable file

       <DestFile>   - resulting file

       ?	    - tells RE that source codepage is unknown and RE should analyze the file and determine the source codepage

       K	    - tells RE that destination codepage is KOI-8

       Note:  If  you  know, what is source codepage, you may use it instead of "?" option. For example, you want to convert letter.txt file which
       was written in Win you know, that this file is in 1251 codepage:

	   re letter.txt letter2.txt W K

       Now examine the letter2.txt - you should see russian symbols in KOI-8.

       Here is the know codepages list and their abbreviatures:
	   W   - Windows 1251	 "_"  - _xxe
	   D   - Dos		 "%"  - %hex
	   K   - KOI-8		 "\" - 'hex
	   L   - Latin		  G   - Graph_win
	   I   - Iso		 "<"  - <binhex>
	   H   - HEX		  +   - +UTF7-
	   S   - ShiftKbrd	  C   - C_MIC
	   M   - Mac		  Y   - Y_c16
	   A   - AFF		  Z   - Z_c32
	   O   - Odd(UTF8_1)	  F   - F(UTF8_2)
	   B   - Base64 	  P   - Pict
	   E   - Express	  N   - N_Estl
	   T   - T-Html 	  V   - V_Vpp855
	   U   - User		  X   - X_sp
	   "-" - uue		  J   - J_diff

       Other options are: [-v][-E|-R|-N][-e|-s]
	    -v - tells what is processing
	    -n - don't tells what is processing (default)
	    -E - converts all p,H from Russian to English
	    -R - converts all p,H from English to Russian
	    -N - lets all p,H Russian or English as in text (default)
	    -e - converts all symbols 0x80 - 0xFF
	    -s - converts only 64 symbols of Russian Alphabet (default)
