If you could clearly state what do you want to achieve, you would get (even more) help. Please note, nobody here is mind-readed or clairvoyant.

Never crossed my mind that sed or awk could not create a line in an empty file and that it needed some text on the file to guide itself during the process of finding the line i wanted , and this is why i assumed automatically that code was not working on the first post i made .

You guys can be sure that i will not be the only one that made this perception error , on the net exists more people with the same perception i had on that tool .

However , i already solved my issue here .

Thanks for all you guys patience on this issue .

My solution to solve that particular issue was to rearrange my original script to put data in the order i needed instead using sed to create change the file . For that i used echo .

example : original order were i needed sed and where sed had to write the first line and other lines in organized order :

5
7
3
1
4

So , i changed my original script and used echo to write the variables i needed to avoid using sed .

1
2
3
4
5
6
7

I was trying originally to use sed because my script have almost 2000 lines and other scripts that work in conjunction with what this script will write .

Well , its complicated but the solution was that one .

You can seed it with 'yes' if you need to do something like that with sed, though there are probably better tools for generating files from templates (which is essentially what we're doing here):
