删除多个 csv 文件的行

Question

I am trying to merge multiple csv files while deleting the 2 first rows of each file. I came up with something like this:

@echo off
(for %%f in (*.csv) do more +2 "%%f") >> output.csv
echo Done.

There are 12 files of 26Mo (253 612 rows in each file). But the process stops at row 65 534, making a 6Mo file.

Answer 1

I think this is the fastest way to do that in a Batch file:

@echo off

(for %%f in (*.csv) do (
   < "%%f" ( 
      set /P "=" & set /P "="
      findstr "^"
   )
)) > output.tmp

ren output.tmp output.csv
