BAT information, it is possible to code a thing like IF ERRORLEVEL..., or with some variations of Home windows, the %ERRORLEVEL% ecosystem variable. Dependent upon the worth, This system checking it may acquire some action. Do Observe as outlined higher than, that 0, EXIT_SUCCESS and EXIT_FAILURE are the moveable productive/unsuccessful values allowed by the regular. Some systems may decide to use other values, each beneficial and unfavorable, but understand that if you use Individuals values, the integrity of Individuals values just isn't something that the Regular controls. Quite simply, exiting with in addition to the transportable values, let us presume values of 99 or -99, may or may not provide the similar final results/intentions on each ecosystem/OS (Put simply, there is no assurance that the 99 or -99 "go anywhere").
