Windows批量比较文件

Question

I have this code, that will compare 4 text files N1.txt N2.txt etc. with out.txt.

set A=4
for /L %%r in (1,1,%A%) do (
   findstr /vxg:N%%r.txt out.txt>>MissingValues.txt
   for /f %%a in ('^<MissingValues.txt find /v /c ""') do echo %%a differences
)

If i run the part inside the for loop alone, it works fine. When i add the for loop, i am just getting the same values inside the text file, and not only the missing values. What is wrong with the code ?

Thanks

I found a code that works for my files, it's a bit slow but works fine for my files.

@echo off

set A=4
for /L %%r in (1,1,%A%) do (
for /f "delims=" %%a in (out.txt) do (
   find "%%a" <"IMSI%%r.txt" || >>result.txt echo %%a
 )
)
