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

Hi,

you didn't provided any example nor further informationen,
how the files should be read. Try:

Code:
num=1 && while read line  
do 
    sed "${num}s/^\(.\{25\}\)........\(.*$\)/\1"${line}"\2/" file
    let num++
done < replacementfile
