How do I get the application exit code from a Windows command line? -


i running program , want see return code (since returns different codes based on different errors).

i know in bash can running

echo $?

what do when using cmd.exe on windows?

a pseudo environment variable named errorlevel stores exit code:

echo exit code %errorlevel%

also, if command has special syntax:

if errorlevel

see if /? details.

example

@echo off my_nify_exe.exe if errorlevel 1 (    echo failure reason given %errorlevel%    exit /b %errorlevel% )

warning: if set environment variable name errorlevel, %errorlevel% return value , not exit code. use (set errorlevel=) clear environment variable, allowing access true value of errorlevel via %errorlevel% environment variable.
