Question

我正在编写一个小程序以获取并保存用户输入，以便可以参考它来更改库存。它将名称另存为Asset_Change。如果前一个存在，我该如何在它将创建新文件名的位置创建它，因此在下次运行该程序时，输出文件将更改为Asset_Change_1或类似的内容。

@echo off
set Output="T:\Helpdesk\Documentation\HDI - Help Desk Inventory\Assets to File into 1213"

set /p Date_Sent=Date Sent: 
set /p Item=Item: 
set /p Model_Number=Model Number: 
set /p Serial_Number=Serial Number: 
set /p Item_Location=Inventory Location: 
set /p Details=Details: 
set /p RMA=RMA Number: 
set /p Repair_Cost=Repair Cost: 
set /p Shipping_Cost=Shipping Cost: 
set /p Date_Received=Date Received: 

echo Date Sent: %Date_Sent% >> %Output%\Asset_Change.txt
echo Item: %Item% >> %Output%\Asset_Change.txt
echo Model Number: %Model_Number% >> %Output%\Asset_Change.txt
echo Serial Number: %Serial_Number% >> %Output%\Asset_Change.txt
echo Item Location: %Item_Location% >> %Output%\Asset_Change.txt
echo Details: %Details% >> %Output%\Asset_Change.txt
echo RMA: %RMA% >> %Output%\Asset_Change.txt
echo Repair Cost: %Repair_Cost% >> %Output%\Asset_Change.txt
echo Shipping Cost: %Shipping_Cost% >> %Output%\Asset_Change.txt
echo Date Received: %Date_Received% >> %Output%\Asset_Change.txt

echo Thank you. This will now close.
pause

每次运行该程序时，当前都会将更改添加到当前的Asset_Change.txt文件中。我基本上希望每次运行时都能创建一个新文件。

有一个简单的解决方案来编号文件。该代码的唯一缺点是，如果有人删除文件2，并且文件1和文件3存在，它将重新创建文件2。我不确定为什么您不选择使用带有文件名的日期和时间戳。

@echo off
set "Output=T:\Helpdesk\Documentation\HDI - Help Desk Inventory\Assets to File into 1213"

set /p Date_Sent=Date Sent: 
set /p Item=Item: 
set /p Model_Number=Model Number: 
set /p Serial_Number=Serial Number: 
set /p Item_Location=Inventory Location: 
set /p Details=Details: 
set /p RMA=RMA Number: 
set /p Repair_Cost=Repair Cost: 
set /p Shipping_Cost=Shipping Cost: 
set /p Date_Received=Date Received: 

SET "num="
set "us="

:loop
IF EXIST "Asset_Change%us%%num%.txt" (
    set /A "num+=1"
    set "us=_"
    goto loop
)
set "file=Asset_Change%us%%num%.txt"

(
echo Date Sent: %Date_Sent%
echo Item: %Item%
echo Model Number: %Model_Number%
echo Serial Number: %Serial_Number%
echo Item Location: %Item_Location%
echo Details: %Details%
echo RMA: %RMA%
echo Repair Cost: %Repair_Cost%
echo Shipping Cost: %Shipping_Cost%
echo Date Received: %Date_Received%
)>>"%Output%\%file%"

echo Thank you. This will now close.
pause

最终代码应类似于：

@echo off
setlocal EnableDelayedExpansion

set "Output=T:\Helpdesk\Documentation\HDI - Help Desk Inventory\Assets to File into 1213"

set /p Date_Sent=Date Sent: 
set /p Item=Item: 
set /p Model_Number=Model Number: 
set /p Serial_Number=Serial Number: 
set /p Item_Location=Inventory Location: 
set /p Details=Details: 
set /p RMA=RMA Number: 
set /p Repair_Cost=Repair Cost: 
set /p Shipping_Cost=Shipping Cost: 
set /p Date_Received=Date Received: 

if exist "%Output%\Asset_Change.txt" (
    set "file=Asset_Change.txt"
) else (
    set "file=Asset_Change_1.txt"
    goto :calc
)

:calc
if exist "%file%" (
    goto :out
) else (
    for /F "tokens=3 delims=_." %%A IN ("%file%") do set "num=%%A"
    set /a "num+=1"
    set "file=Asset_Change_!num!.txt"
)
goto :calc

:out
(
echo Date Sent: %Date_Sent%
echo Item: %Item%
echo Model Number: %Model_Number%
echo Serial Number: %Serial_Number%
echo Item Location: %Item_Location%
echo Details: %Details%
echo RMA: %RMA%
echo Repair Cost: %Repair_Cost%
echo Shipping Cost: %Shipping_Cost%
echo Date Received: %Date_Received%
)>>"%Output%\%file%"

echo Thank you. This will now close.
pause

这是我找到的最佳解决方案。我知道它很复杂，但是我无法进一步简化它。

输入cmd：

for /?
setlocal /?
if /?
set /?
goto /?
