WMIC - 蝙蝠文件菜单程序

Question

我想写一个批处理文件，通过选择一个数字来卸载程序。我不知道如何计算操作系统中的多少程序，然后以MENU格式将数字分配给所有程序。我不想输入程序的所有字母。

复制和过去下面的程序到记事本并保存为GUninstall.bat

@Echo off 
Echo This is a batch file uninstallation program. 
Echo Run as administrator WMIC will not work. 
echo. 
Echo The command [wmic product get name] will run. 
Echo Looking up all installed programs... 
echo. 
wmic product get name 

echo 1. First program 
echo 2. Second program 
echo 3. Third program 
echo 4. Fourth program 
echo 5. Fifth program 
echo. 
@echo Pick a number: 
echo. 
choice /c:12345 

if "%errorlevel%"=="1" wmic product where name="First program" call uninstall 
if "%errorlevel%"=="2" wmic product where name="Second program" call uninstall 
if "%errorlevel%"=="3" wmic product where name="Third program" call uninstall 
if "%errorlevel%"=="4" wmic product where name="Fourth program" call uninstall 
if "%errorlevel%"=="5" wmic product where name="Fifth program" call uninstall 

Echo. 
Echo. 

@echo First method is done. I'll go into the alternate method. 

pause 
Echo Get user input - program name? 
Echo. 
Echo This is an alternate method 
:input 
set INPUT= 
set /P INPUT=Uninstall which program?: %=% 
if "%INPUT%"=="" goto input 
echo Your input was: %INPUT% 

echo. 
echo. 
Echo Uninstalling... 

echo The command [wmic product where name="%INPUT%" call uninstall] will run. 


wmic product where name="%INPUT%" call uninstall 

@echo If there is "no instance" errors, then the program %INPUT% was uninstalled. 

pause 

Answer 1

FOR -Loops大多为你的问题的答案。

A FOR/F -loop可以收集所有程序并对它们进行计数。

set count=0 
for /F "delims=" %%A in ('wmic product get name') do (
    set /a count+=1 
    setlocal EnableDelayedExpansion 
    for %%n in (!count!) do (
    endlocal 
    set product[%%n]=%%A 
    echo %%n. %%A 
) 
) 

，以后你可以从阵列通过

SET /p uninstallNr=Uninstall number: 
setlocal EnableDelayedExpansion 
ECHO !product[%uninstallNr%]!
