我的本意是问一问
每一行都用echo的形式怎么输出。这个more的用法我赚到了！！

我这个批处理后面还有其他命令呢 ，用2楼的方法不是把批处理自身的命令也写进txt里面了？

你改成+5看看效果

+5的方法我试了，还是取到文件末尾啊
我不想取道文件末尾，只想截取一个批处理文件中间的几行，用这个命令还行吗

用echo语句一行一行的写上述bat命令如何实现

我如果写echo set num=0就会输入为空我要是写echo “set num=0”就会多出双引号
要把命令写进文本就那么难吗

echo set num=0 >a.txt

echo set num=0 > a.txt
echo setlocal enabledelayedexpansion >> a.txt
echo for /f "delims=" %%%%i in (input.txt) do call :intercept "%%%%i" >> a.txt
echo echo value=%%str_%% >> a.txt
echo pause >> a.txt
echo goto :eof >> a.txt
echo. >> a.txt
echo :intercept >> a.txt
echo set str=%%1 >> a.txt
echo set str=%%str:~2,-2%% >> a.txt
echo if not "%%str%%"=="" echo. "%%str:~0,1%%"^|findstr "[0-9]"^>nul ^&^& ( >>a.txt
echo set num=1^&set str_=!str_!%%str:~0,1%%^&^&call :intercept " !str:~1! ")^|^|( >>a.txt
echo if %%num%% equ 0 call :intercept " !str:~1! " >> a.txt
echo ) >> a.txt
echo goto :eof >> a.txt

我总结的经验是><|&用^>^<^|^&来替换，%用%%来替换

顶下人气

学到了！

echo set num=0 >a.txt 执行的结果：set num=0的后面有一个空格这会影响数据的使用，解决办法：
(echo set num=0)>a.txt
