Append lines of text file with lines from another text file

Question

I only have access to windows and its command line.

I have two text files with many lines, file1 and file2. I want to append the lines in file1 with the corresponding lines from file2.

Each line in file1 looks like this:

apple Orange

Each line in file2 looks like this:

banana

I want the output to look like this:

apple Orangebanana

Any ideas? Preferably via win command prompt?

Answer 1

This uses file1.txt and file2.txt as input files and interleaves them into result.txt

@echo off
setlocal DisableDelayedExpansion
(
< file2.txt (
   for /F "delims=" %%a in (file1.txt) do (
      set file2Line=
      set /P file2Line=
      set "file1Line=%%a"
      setlocal EnableDelayedExpansion   
      echo(!file1Line!!file2Line!
      endlocal
   )
)
)>"result.txt"
