如何在Windows批处理中执行while循环

Question

我编写了一个 Windows 批处理脚本来根据我放入名为 list.txt 的记事本文件中的列表检查文件并将其移动到另一个目录。但我不知道如何设置while循环。只有条件满足才跳出子路由。

在 C 编程中，我们可以通过直接设置 while 循环来编写这样的代码。但似乎在 windows 批处理中是完全不同的。

我想要的是这样的：

目录A：

 1. A.txt 
 2. B.txt 
 3. list.txt (By line sequential with filename want to move) 
 4. process.bat

目录 B：

1. 没有文件（然后按 list.txt 中设置的行顺序移动文件）或
2. A.txt（如果目录中已经存在文本文件，则process.bat会在A.txt消失之前暂停）

Process.bat

@echo off

:readline
for /f "tokens=*" %%a in (list.txt) do call :processline %%a

goto :eof

:processline
if exist D:\DirectoryA\*.txt (
echo %time% >> D:\AutoLog\Log.txt
echo Previous job did not finished yet. >> D:\AutoLog\Log.txt
Timeout /t 30 
echo.
)
set name=%*
if exist %name%.txt (
echo %time% >> D:\AutoLog\Log.txt
echo File found and processing   %name%.txt   now... >> D:\AutoLog\Log.txt
copy "%~dp0\%name%.txt" "D:\DirectoryB"
echo Transfer   %name%.txt   completed!! >> D:\AutoLog\Log.txt
echo. >> D:\AutoLog\Log.txt
Timeout /t 790
echo.
echo ==============================================================
)

:eof

请指导我使用 while-loop 方法完成脚本。谢谢

Answer 1

我更改了一些脚本序列，它现在可以工作了。

@echo off

:readline
for /f "tokens=*" %%a in (list.txt) do call :processline %%a

goto :eof

:processline
set name=%*
if exist C:\Test2\*.txt (
        echo %date% %time% >> C:\Test2\Log.txt
        echo Previous job did not finished yet. >> C:\Test2\Log.txt
        Timeout /t 5
        echo.
        echo. >> C:\Test2\Log.txt
        goto :processline
         )
if exist %name%.txt (
echo %date% %time% >> C:\Test2\Log.txt
echo File found and processing   %name%.txt   now... >> C:\Test2\Log.txt
copy "%~dp0\%name%.txt" "C:\Test2"
echo Transfer   %name%.txt   completed!! >> C:\Test2\Log.txt
echo. >> C:\Test2\Log.txt
Timeout /t 10
echo.
echo ==============================================================
)

:eof

这将复制并计算文本文件中的行数..

@ echo off 
:TextPath
cls
set /p Input=#1 Enter the full path of the text file :
set /p Source=#2 Enter the full path of Source :
set /p Target=#3 Enter the full path of Destination :

:choice
set /P c=Ready to Continue[Y/N]?
if /I "%c%" EQU "Y" goto :Yes
if /I "%c%" EQU "N" goto :No
goto :choice

:Yes_Local
for /f "delims=" %%i in (%Input%) do echo f| xcopy /f /y  "%Source%\%%i" "%Target%\%%i"
for /f %%C in ('Find /V /C "" ^< %Input%') do set Count=%%C
msg * No of Lines executed= %Count%
exit

:No
cls
color e
echo Redirecting to Main....
PING 127.0.0.1 -n 2 >NUL
cls
echo Please wait
PING 127.0.0.1 -n 4 >NUL
goto TextPath
