我编写了一个批处理文件,该文件在两个文件夹路径中查找可执行文件,然后运行它。我刚开始编写批处理文件,并被告知这很草率,可以使用if / else语句更好地编写。
@echo off
Taskkill /im firefox.exe >nul 2>nul
echo Remove and re-install Mozilla Firefox
"C:\program files\Mozilla Firefox\uninstall\helper.exe" /s
"C:\program files (x86)\Mozilla Firefox\uninstall\helper.exe" /s
到目前为止,我发现没有任何东西似乎起作用。这是最后一次无效的尝试;
@echo off
Taskkill /im firefox.exe >nul 2>nul
echo Remove and re-install Mozilla Firefox
IF exist helper.exe /s ( "C:\program files\Mozilla Firefox\uninstall\
) else helper.exe /s ( "C:\program files (x86)\Mozilla firefox\uninstall\
)
答案 0 :(得分:1)
您可以这样做:
@echo off
taskkill /im firefox.exe >nul 2>nul
echo Remove and re-install Mozilla Firefox
if exist "C:\program files\Mozilla Firefox\uninstall\helper.exe" (
"C:\program files\Mozilla Firefox\uninstall\helper.exe" /s
) else (
"C:\program files (x86)\Mozilla firefox\uninstall\helper.exe" /s
)
但您实际上并不需要else
语句:
@echo off
taskkill /im firefox.exe >nul 2>nul
echo Remove and re-install Mozilla Firefox
if exist "C:\program files\Mozilla Firefox\uninstall\helper.exe" /s
if exist "C:\program files (x86)\Mozilla firefox\uninstall\helper.exe" /s
或
"C:\program files\Mozilla Firefox\uninstall\helper.exe" /s || "C:\program files (x86)\Mozilla firefox\uninstall\helper.exe" /s
甚至更好的是,在环境中找到Firefox的路径(如果安装正确)并使用它的路径:
@echo off
taskkill /im firefox.exe >nul 2>nul
echo Remove and re-install Mozilla Firefox
for /f "delims=" %%i in ('where firefox.exe') do (
"%%~dpihelper.exe" /s
)
