Parsing 2 text files using cmd or batch

Question

I'm trying to parse 2 text files and make one with information from both files using cmd or batch, is it possible without using any other program or vbscript? Here is the example: `number.txt` contains ``` ren 01.mp3 ren 02.mp3 ren 03.mp3 ``` and so on... `names.txt` contains ``` Chapter_00_Introduction.mp3 Chapter_01_This_is_Chapter_01.mp3 Chapter_02_This_is_Chapter_02.mp3 Chapter_03_This_is_Chapter_03.mp3 ``` and so on... What I'd like is to produce a third file (output.txt) with this content ``` ren 01.mp3 Chapter_00_Introduction.mp3 ren 02.mp3 Chapter_01_This_is_Chapter_01.mp3 ren 03.mp3 Chapter_02_This_is_Chapter_02.mp3 ``` and yes, the names are mismatched (`01.mp3` is actually the introduction, `02.mp3` is the chapter 1 and so on). This is what I have so far: ``` @echo off setLocal EnableDelayedExpansion for /f "tokens=*" %%a in (Number.txt) do ( For /f "tokens=*" %%b in (Names.txt) Do (Echo %%a%%b.mp3>>output.txt) ) Exit ``` The result is ``` Ren 01.mp3 Chapter_00_Introduction…

Accepted Answer

```
@echo off
setLocal EnableDelayedExpansion
< Names.txt (
   for /f "tokens=*" %%a in (Number.txt) do (
      set /P name=
      Echo %%a !name!
   )
) >output.txt
Exit
```
