Question

我需要通过运行.bat文件来检查任何Windows系统中的可用浏览器。批处理文件应该能够检查系统中是否安装了Firefox和Chrome或任何其他浏览器。否则我想打开默认浏览器。

if exist "C:\Program Files(x86)\Mozilla Firefox\firefox.exe" start firefox.exe

这是一种方法，但如果安装在其他位置完成，则无法正常工作。

Answer 1

我建议使用HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet键。它列出了已在系统上注册的Web浏览器客户端，并提供了哪一个是默认设置，以及在系统中找到每个客户端的位置。

这里只是一个例子，我把它们放在一起来说明如何使用这些信息。根据您的需要或根据您的要求进行调整。

@echo off
setlocal EnableDelayedExpansion
:Menu
echo 32-bit
set "Count=1"
for /f "tokens=2,*" %%A in ('reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Clients\StartMenuInternet" /ve 2^>nul') do set "Default=%%B"
for /f "skip=3 delims=" %%A in ('reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Clients\StartMenuInternet" 2^>nul') do (
    if "%%~nxA"=="%Default%" (
        echo !Count!. %%~nA [Default]
    ) else (
        echo !Count!. %%~nA
    )
    set /a "Count+=1"
)
echo.
echo 64-bit if 32-bit above, else 32-bit
for /f "tokens=2,*" %%A in ('reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet" /ve 2^>nul') do set "Default=%%B"
for /f "skip=3 delims=" %%A in ('reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet" 2^>nul') do (
    if "%%~nxA"=="%Default%" (
        echo !Count!. %%~nA [Default]
    ) else (
        echo !Count!. %%~nA
    )
    set /a "Count+=1"
)
echo.
:Input
set "Input="
set /p "Input=> Select a Browser: "
if not defined Input goto Input
set "Input=%Input:"=%"
set "Count=1"
:: NOTE if the browser name is typed out and matching on the name then the last match will be chosen.
:: As it is currently setup this means that the 32-bit version will always win on a name match.
for /f "skip=3 delims=" %%A in ('reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet" 2^>nul') do (
    if /i "%Input%"=="%%~nA" set "Choice=%%~A"
    if "%Input%"=="!Count!" set "Choice=%%~A"
    set /a "Count+=1"
)
for /f "skip=3 delims=" %%A in ('reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Clients\StartMenuInternet" 2^>nul') do (
    if /i "%Input%"=="%%~nA" set "Choice=%%~A"
    if "%Input%"=="!Count!" set "Choice=%%~A"
    set /a "Count+=1"
)
if not defined Choice goto Menu
for /f "tokens=2,*" %%A in ('reg query "%Choice%\shell\open\command" /ve 2^>nul') do set "Command=%%~B"
start "Browser" "%Command%"
endlocal
echo Done
pause>nul

您最终需要以管理员身份启动它，因为它从注册表中导出值。我没有使用REG命令来实现最大兼容性：

@echo off
START /W REGEDIT /E "%Temp%.\BROW.reg" HKEY_CURRENT_USER\Software\Classes

setlocal enableDelayedExpansion
for /f "tokens=4 delims=\" %%B in ('type %Temp%.\BROW.reg ^| findstr  /E  "HTML\shell]"') do (
 set "browser=%%B"
 echo !browser:~0,-4!
)
endlocal

del /Q /F "%Temp%.\BROW.reg"

修改

@echo off setlocal enableExtensions echo. echo. echo INSTALLED BROWSERS echo. echo. rem ::::::::::::::::::::::::::::::::::::::::::::::::::::: rem :: exporting registry values for installed browsers rem ::::::::::::::::::::::::::::::::::::::::::::::::::::: rem for 64 bit systems START /W REGEDIT /E "%Temp%\BROW3.reg" HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Clients\StartMenuInternet rem for 32 bit systems if not exist "%Temp%\BROW3.reg" START /W REGEDIT /E "%Temp%\BROW3.reg" HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet setLocal enableDelayedExpansion for /f "tokens=*" %%B in ('type "%Temp%\BROW3.reg" ^| findstr /E "DefaultIcon]"') do ( rem extracting browser name from icon path set "browser=%%B" rem removing \DefaultIcon] string set "browser=!browser:\DefaultIcon]=!" rem get the browser name for %%P in ("!browser!") do echo %%~nP ) endLocal echo. echo. echo EXECUTABLES PATHS echo. echo. setLocal enableDelayedExpansion for /f "tokens=* delims=@=" %%B in ('type "%Temp%\BROW3.reg" ^| findstr /B "@" ^| findstr /E ".exe\\\",0\"^"') do ( set "browser=%%~B" set "browser=!browser:\\=\!" echo !browser! ) setLocal enableDelayedExpansion for /f "tokens=* delims=@=" %%B in ('type "%Temp%\BROW3.reg" ^| findstr /B "@" ^| findstr /E ".exe,0\"^"') do ( set "browser=%%~B" set "browser=!browser:\\=\!" set "browser=!browser:,0=!" echo !browser! ) endLocal rem delete temp file del /Q /F "%Temp%\BROW3.reg" echo. echo. echo DEFAULT BROWSER echo. echo.
