[文本处理] 数据在txt或者是cvs文件中，如何用批处理变成四个一行排列？

@echo off
set "MergeRows=4"
(for /f  %%a in (a.txt) do (
    set /a n+=1
    set /a m=n%%%MergeRows%
    set /p=%%a    <nul
    set /a test=1/m 2>nul || echo;
))>b.txt

@echo off
echo.

set /a sum=0
for /l %%n in (1,1,50) do (
if exist %%n.log (
find "Sum of electronic and zero-point Energies" %%n.log >>thermalchemistry.txt
find "Sum of electronic and thermal Energies" %%n.log >>thermalchemistry.txt
find "Sum of electronic and thermal Enthalpies" %%n.log >>thermalchemistry.txt
find "Sum of electronic and thermal Free Energies" %%n.log >>thermalchemistry.txt
set /a sum=sum+1
)
