There is something i don't understand tough:
In the mail you sent in the URL showed above, you write that we:
"can't edit files with KIX, the only thing you can do is to write the contents of the file to change in a temp file and change the line you want, then delete the input file and rename the temp file"
If i inderstand well, it means that you get ALL the data of the original file in the temp AND during the process you erase the uncorrect line for the new one.
If i used your script well, all i have left on the new config.nt is one line: files=200. Everything else is lost.

Did i missed something here?
