如何在调用循环中完全停止批处理文件？
exit/b 只是退出 :label 循环，而不是整个批处理文件，而 bare exit 退出批处理文件 和 父 CMD外壳，这是不需要的。
@echo off
call :check_ntauth
REM if check fails, the next lines should not execute
echo. ...About to "rmdir /q/s %temp%\*"
goto :eof
:check_ntauth
if not `whoami` == "nt authority\system" goto :not_sys_account
goto :eof
:not_sys_account
echo. &echo. Error: must be run as "nt authority\system" user. &echo.
exit /b
echo. As desired, this line is never executed.
结果:
d:\temp>whoami
mydomain\matt
d:\temp>break-loop-test.bat
Error: must be run as "nt authority\system" user.
...About to "rmdir /q/s d:\temp\systmp\*" <--- shouldn't be seen!
最佳答案
您可以从 :not_sys_account 子例程中设置 ERRORLEVEL 并将其用作返回值。主程序可以检查这一点并改变它的行为:
@echo off
call :check_ntauth
REM if check fails, the next lines should not execute
if errorlevel 1 goto :eof
echo. ...About to "rmdir /q/s %temp%\*"
goto :eof
:check_ntauth
if not `whoami` == "nt authority\system" goto :not_sys_account
goto :eof
:not_sys_account
echo. &echo. Error: must be run as "nt authority\system" user. &echo.
exit /b 1
echo. As desired, this line is never executed.
与原始代码的区别在于 exit/b 1 现在指定了一个 ERRORLEVEL 并且检查 if errorlevel 1 goto :eof 终止设置了 ERRORLEVEL 时的脚本。
