batch-file - 批量.txt阅读器

Question

所以，基本上我想要一个批处理文件来读取 .txt。问题是每次将新行写入 .txt 时，批处理文件都需要更新

@echo off
set "pc=%1"
FOR /F "delims=:" %%A IN ('findstr /N .* "%pc%"') DO set "zeilen=%%A" 
type %pc%
set /A zeilen1=%zeilen%
:loop
if not %zeilen% == %zeilen1% (
set "line="
set zeilen2=%zeilen% - 1
for /f %%a in ('more/e +%zeilen2% ^< %pc%') do (
   if not defined line set "line=%%a"
)
 echo %line%   
 set /A zeilen+=1
)
FOR /F "delims=:" %%A IN ('findstr /N .* "%pc%"') DO set "zeilen1=%%A
goto loop

我也无法使用 type 命令(第 9-13 行)，因为我不想只刷新整个 .txt 最后一行。

抱歉我的英语很差

谢谢

要启动批处理，您需要执行以下操作调用batch.cmd txtname.txt

Answer 1

基本的 tail 命令可以这样写。感谢 @dbenham 在 DosTips.com 上的初步解决方案

@echo off
call :Loop <"tailme.txt"

exit

:Loop
set "line="
set /p "line="
if defined line (
  echo %line%
) else (
  pathping -q 1 -p 300 localhost >nul
)
goto :loop
