我正在尝试使用Windows批处理脚本将abc.txt的一部分复制到def.txt文件。

的abc.txt

简而言之，我想跳过具有字符串＆＃34;导出＆＃34;的行。并将结果移动到def.txt。我尝试使用for /F但无法实现这一点。能否请你帮忙。提前谢谢。

Answer 1

findstr /v /c:"exporting" abc.txt > def.txt

无需迭代文件。只需过滤输入文件中与包含指定文字的条件不匹配（/v）的行，并将输出发送到指定的文件。

已修改以适应评论

@echo off
    setlocal enableextensions disabledelayedexpansion
    > def.txt (
        for /f "tokens=1,* delims=:. " %%a in ('
            findstr /n "^" abc.txt
        ') do echo(%%b
    )

此处文件由findstr处理以对行进行编号（以保留源文件中的空行），输出由for /f命令delims和{{1}处理}子句配置为删除输出行中的起始空格/点/冒号。

Answer 2

这与MC ND的解决方案没有实际区别 - 但它是另一种选择：它目前区分大小写，但有一个/i切换来改变它。

find /v "exporting" < abc.txt > def.txt

使用文件中的特定字符串跳过行 - 批处理脚本
