Hi guys

I having som problem trying to use sed to get a file and insert inside another one. I'll try to explain better.

I have a base.txt and using sed(having a array variables) I'm chaging some strings inside this file and saving as base1.txt. until here okay.
Then, I have to get this base1.txt and insert it inside another file called script.txt.
Well, If I didn't have any looping so far so good. Then, when the script restart, it has to change the base file again, with a different variable(until here okay), and then get this base1.txt again and insert at the same old file script.txt.

The problem is, Sed cleans out the file when I overwrite it. I tried to rename files, but I just can't reach the logic of doing this...
Any suggestion would be a lot appreciatted.

Thank you in advance.
