我想用批處理實現向s.txt中多次分別導入文本例如：“aaaa","bbbb","cccc","dddd"
實現s.txt內效果如：
aaaabbbbccccdddd
可是echo命令每次導入的時候會強制換行，如：
aaaa
bbbb
cccc
dddd
我該怎么實現我想要的一行效果呢？謝謝！
答案：
echo 做不到，不過可以執行以下語句到達到目的
>>s.txt set /p="aaaa" <nul
>>s.txt set /p="bbbb" <nul
>>s.txt set /p="cccc" <nul
>>s.txt set /p="dddd" <nul
s.txt的內容將是 aaaabbbbccccdddd
注1:“ >>s.txt”這里是輸出流定向的意思，把輸出流重定到了s.txt文件，“<nul ”則是把輸入流指定成了nul，所以set/p="aaaa"就不用等待用戶輸入了。
其實把寫文件操作放到后面更容易讓人理解些：set /p="aaaa"<nul>>s.txt
注2：關于set/p="aaaa"的詳細內容請查看《set命令》
實例1：
if exist %statFile2% ( >>%statFile2% set/p=,%%i<nul ) else ( >>%statFile2% set/p=%%i<nul )
實例2 ----(個人添加)
@echo off
del b.txt
del c.txt
del d.txt
if exist "%cd%/zhI386" rd /s /q "%cd%/zhI386"
md zhI386
::for /r "%cd%/eni386/" %%i in (*) do (echo %%i>>b.txt)
for /f %%i in ('dir /b %cd%/eni386/') do (
echo %%i>>c.txt
if exist "%cd%/zhall/i386/%%i" (copy "%cd%/zhall/i386/%%i" "%cd%/zhI386/"
) else (>>d.txt set /p="zhall/i386/%%i"<nul&echo ----Not exist>>d.txt)
)
windows批處理之六-echo輸出不換行
完整案例：
Code:
@echo off
set /p="hello "<nul
set /p="world "<nul
echo again
echo new line
Result:
hello world again
new line
應用：
echo off
set csvpath=測試數據
set sqluldr=D:/sqluldr/sqluldr2sdk/sqluldr2
set sqlpath=導出模板
rem set filename=產品行情
rem sqluldr2 gtcustomer/passwd file=%csvpath%/%filename%.csv text=csv field=, sql=exp%filename%.sql log=%csvpath%/%filename%.log
rem
rem set filename=產品行情更新
rem sqluldr2 gtcustomer/passwd file=%csvpath%/%filename%.csv text=csv field=, sql=exp%filename%.sql log=%csvpath%/%filename%.logset expfpath=百萬級
echo 導出%expfpath%數據：
for %%i in (%sqlpath%/%expfpath%/exp*.sql) do (
set /p="導出數據: %%~ni"<nul
%sqluldr% gtcustomer/passwd file=%csvpath%/%expfpath%/%%~ni.csv text=csv field=, sql=%%i log=%csvpath%/%expfpath%/%%~ni.log
echo ............ok.
)
set expfpath=千萬級
echo 導出%expfpath%數據：
for %%i in (%sqlpath%/%expfpath%/exp*.sql) do (
set /p="導出數據: %%~ni"<nul
%sqluldr% gtcustomer/passwd file=%csvpath%/%expfpath%/%%~ni.csv text=csv field=, sql=%%i log=%csvpath%/%expfpath%/%%~ni.log
echo ............ok.
)
