I would like to add a predefined text to each new line on a text file and create a new text file with the added text. Please help.

A:
In Windows, this will do it:
(for /f "delims=" %L in (oldfile.txt) do @echo predefined text %L)> newfile.txt
Note that in a batch file you'll need to use double % signs:
(for /f "delims=" %%L in (oldfile.txt) do @echo predefined text %%L)> newfile.txt
Note also that if you don't put the ">" right after the %L, you will get a space after every line. If you use ">>" instead of ">" you will keep adding on to newfile.txt instead of creating a new one each time you run it.

Note that %L works when you type this line in on the command line. If you want to put it in a batch or cmd file, you need two percent signs on L. So it'd be %%L instead of %L.

Edited slightly for correctness and noting other issues. Hope you don't mind.

*sigh* ok, I'll refrain from editing, then. In this form it's incorrect, you know? Just try it with a file that contains more than just a single line of text. Agreed though, that digits don't cause harm in this specific case.

Johannes was right...you need parens or the redirection applies to the echo instead of the for.
