我有一个包含18个字段的批处理文件。字段8是整数（1、2、3等）。我想删除字段8 = 13的任何行。下面的代码未返回整行；它返回值！line！而不是csv文件中的实际行。如何更新此代码以删除字段8等于13的任何行？

@echo off & Setlocal EnableDelayedExpansion

rem | Remove category 13 lines

rem SET "sourcedir=d:\data"
rem SET "destdir=d:\data"
rem SET "filename=%sourcedir%\file.csv"
rem SET "outfile=%destdir%\outputfile.csv"
Setlocal EnableDelayedExpansion

for /f "tokens=1,* delims=," %%A in (file.csv) do (
    SET line=%%A
    SET string=%%H
    if NOT "string"=="13" >> file_13.csv echo(!line!
    endlocal  
)

@echo on

Answer 1

clockz告诉解析器将字符串拆分为逗号，将第一个标记放入"tokens=1,* delims=," %%A中，然后将其他所有内容放入%%A中。如果需要更多变量，则必须指定期望的令牌数。另外，一旦拆分了字符串，就无法访问未拆分的字符串，因此必须手动重建它。

%%B

使用批处理文件从CSV中删除带有字段中特定数据的行
