[文本处理] 批处理如何循环读取txt文件

123rt

代码如下

for /f "delims= " %%i in (z.txt) do del %%i.bat
for /f "delims= " %%i in (z.txt) do echo goto start>>%%i.bat
for /f "delims= " %%i in (z.txt) do echo :start>>%%i.bat
for /f "delims= " %%i in (z.txt) do echo a.exe %%i %%i.bat
for /f "delims= " %%i in (z.txt) do echo if errorlevel 1 goto exit>>%%i.bat
for /f "delims= " %%i in (z.txt) do echo if errorlevel 0 goto d>>%%i.bat
for /f "delims= " %%i in (z.txt) do echo :d>>%%i.bat
for /f "delims= " %%i in (z.txt) do echo (echo %%i^>^>a.txt)>>%%i.bat
for /f "delims= " %%i in (z.txt) do echo goto exit>>%%i.bat
for /f "delims= " %%i in (z.txt) do echo :exit>>%%i.bat
for /f "delims= " %%i in (z.txt) do echo exit>>%%i.bat
for /f "delims= " %%i in (z.txt) do start %%i.bat
exit

从z.txt中读取参数给a.exe，把成功的结果输出到a.txt中，现在问题是，z.txt中有几千行的参数，那么运行后，就会产生几千个bat，怎么能设定一次读取100个，完成后继续往下执行，知道读取全部z.txt中的参数，请各位大虾们指教！

由于你要判断a.exe的结果再输出.所以我觉得用两个批好点
第一个,实现每次100个输出,保存任意名字.

@echo off
setlocal enabledelayedexpansion
set n=0

for /f "delims=" %%a in (z.txt) do (
if /i "!n!" neq "100" (
start "" "a.bat" "%%a"
set /a n=n+1
) else (
"a.exe" "%%a"
if /i "%errorlevel%" equ "0" (
echo %%a >> "a.txt"
)
set n=0
)
)
复制代码

第二个保存为a.bat,

@echo off
cd /d "%~dp0"
a.exe %1
if /i "%errorlevel%" equ "0" (
echo %1 >> a.txt
)
复制代码

这种方法我没有实测过.~~估计有问题.~~哈哈,可以当做参考.~
