Errorlevel" command. Assuming your executable returns a non-0 exit code on failure, you do something like: myProgram.exe if errorlevel 1 goto somethingbad echo Success! exit :somethingbad echo Something Bad Happened. Errorlevel checking is done as a greater-or-equal check, so any non-0 exit value will trigger the jump. Therefore, if you need to check for more than one specific exit value, you should check for the highest one first. share|improve this answer answered Aug 10 '10 at 18:20 Hellion 1,2481527 2 Also, since around Windows 2000, there's a "virtual" environment variable called %ERRORLEVEL% that can be tested with ==, EQU, LSS, etc. –Jim Davis Aug 10 '10 at 19:13 Perfect! Thanks. –Dlongnecker Aug 10 '10 at 21:24 2 Oh, for posterity, to make it stop on error, after :somethingbad, use a "pause" command –Dlongnecker Aug 11 '10 at 20:08 2 You don't want to use exit in there as that kills the shell. Either use goto :EOF or exit /b so that just the batch file terminates. –Joey Aug 11 '10 at 21:44 @Jim: You should always delete that variable with set ERRORLEVEL= at the start of your batch if you intend to use it, as the function o

execution to the world. Sadly, even skilled Windows programmers overlook the importance of return codes. Return Code Conventions By convention, command line execution should return zero when execution succeeds http://stackoverflow.com/questions/3452046/get-error-code-from-within-a-batch-file and non-zero when execution fails. Warning messages typically don’t effect the return code. What matters is did the script work or not? Checking Return Codes In Your Script Commands The environmental variable %ERRORLEVEL% contains the return code of the last executed program or script. A very helpful feature is the built-in DOS commands like ECHO, IF, and http://steve-jansen.github.io/guides/windows-batch-scripting/part-3-return-codes.html SET will preserve the existing value of %ERRORLEVEL%. The conventional technique to check for a non-zero return code using the NEQ (Not-Equal-To) operator of the IF command: IF %ERRORLEVEL% NEQ 0 ( REM do something here to address the error ) Another common technique is: IF ERRORLEVEL 1 ( REM do something here to address the error ) The ERRORLEVEL 1 statement is true when the return code is any number equal to or greater than 1. However, I don’t use this technique because programs can return negative numbers as well as positive numbers. Most programs rarely document every possible return code, so I’d rather explicity check for non-zero with the NEQ 0 style than assuming return codes will be 1 or greater on error. You may also want to check for specific error codes. For example, you can test that an executable program or script is in your PATH by simply calling the program and checking for return code 9009. SomeFile.exe IF %ERRORLEVEL% EQU 9009 ( ECHO error - S

Description Every command or script returns with the status of execution, which is referred as return status or exit codes. A successful command returns a 0 while an unsuccessful one returns a non-zero value that usually can be interpreted as an Error Code. The last command executed in the function or the script determines the exit status. This document provides steps on how to return the error codes on .vb scripts, Powershell scripts and batch files. Steps Exit codes for batch files Use the command EXIT /B %ERRORLEVEL% at the end of the batch file to return the error codes from the batch file EXIT /B at the end of the batch file will stop execution of a batch file. use EXIT /B < exitcodes > at the end of the batch file to return custom return codes. Environment variable %ERRORLEVEL% contains the latest errorlevel in the batch file,which is the latest error codes from the last command executed. To know about Environment variable see the below note. Note: Environment variables are a set of dynamic named values that can affect the way, running processes will behave on a computer. For example, an environment variable with a standard name can store the location that a particular computer system uses to store user profile this may vary from one computer system to another. In the batch file , it is always a good practice to use environment variables instead of constant values. Since the same variable get expanded to different values on different computers. Ex
