Looping and using Sed

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.

NWBPSET(1)							      nwbpset								NWBPSET(1)

NAME
nwbpset - Create a bindery property or set its value SYNOPSIS
nwbpset [ -h ] [ -S server ] [ -U user name ] [ -P password | -n ] [ -C ] DESCRIPTION
nwbpset Reads a property specification from the standard input and creates and sets the corresponding property. The format is determined by the output of 'nwbpvalues -c'. nwbpset will hopefully become an important part of the bindery management suite of ncpfs, together with 'nwbpvalues -c'. See util/nwbpsecurity for an example. As another example, look at the following command line: nwbpvalues -t 1 -o supervisor -p user_defaults -c | sed '2s/.*/ME/'| sed '3s/.*/LOGIN_CONTROL/'| nwbpset With this command, the property user_defaults of the user object 'supervisor' is copied into the property login_control of the user object 'me'. nwbpvalues -t 1 -o me -p login_control -c | sed '9s/.*/ff/'| nwbpset This command disables the user object me. Feel free to contribute other examples! nwbpset looks up the file $HOME/.nwclient to find a file server, a user name and possibly a password. See nwclient(5) for more information. Please note that the access permissions of $HOME/.nwclient MUST be 600 for security reasons. OPTIONS
-h -h is used to print out a short help text. -S server server is the name of the server you want to use. -U user user is the user name to use for login. -P password password is the password to use for login. If neither -n nor -P are given, and the user has no open connection to the server, nwbpset prompts for a password. -n -n should be given if no password is required for the login. -C By default, passwords are converted to uppercase before they are sent to the server, because most servers require this. You can turn off this conversion by -C. AUTHORS
