Hi all,

Many thanks for this. It helped me a lot.
I had an error message because the command couldn't parse something

So I slightly changed it and it worked out

sed '3s/^\(...........................\)TOCHANGE\(.*\)/\1ABCABCAB\2/;4,'"$(( $(wc -l < filename )-2 ))"'s/^\(.................\)TOCHANGE\(.*\)/\1ABCABCAB\2/' filename

Again , many thanks for your help
