优化这个代码将目录改成读取当前文件下目录setlocal enabledelayedexpansion set file="E:\labelprint\1.txt" echo. set replaced=1234 echo 1234>"E:\labelprint\2.txt" echo. set all= set /p all=請輸入條碼: for /f "delims=" %%i in ('type "%file%"') do ( set str=%%i set "str=!str:%replaced%=%all%!" echo !str!>>"E:\labelprint\2.txt" ) COPY "E:\labelprint\2.txt" LPT1 goto :1

这是优化后的代码，可以读取当前文件夹下的目录，并使用相对路径：

setlocal enabledelayedexpansion
set file="%~dp0\1.txt"
echo.
set replaced=1234
echo 1234>"%~dp0\2.txt"
echo.
set all=
set /p all=請輸入條碼:

for /f "delims=" %%i in ('type %file%') do (
set str=%%i
set "str=!str:%replaced%=%all%!"
echo !str!>>"%~dp0\2.txt"
)

COPY "%~dp0\2.txt" LPT1
goto :1
