Return Code Conventions By convention, command line execution should return zero when execution succeeds and non-zero when execution fails. Batch File Exit Code 1 With older wait interfaces, the visible exit code only contains the low 8 bits of the exit code.

For example, it is common programming practice for a child process to return zero to the parent signifying success. But you really need to know what the program returns on errors. Sadly, even skilled Windows programmers overlook the importance of return codes. The request cannot be fulfilled by the server R.

Consider using !errorlevel! Windows Errorlevel To execute a follow-on command after failure, we use the || operator: SomeCommand.exe || ECHO SomeCommand.exe failed with return code %ERRORLEVEL% I use this technique heavily to halt a script when See "if /?". 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.

  3. POSIX-compatible systems typically use a convention of zero for success and non zero for error.[8] Some conventions have developed as to the relative meanings of various error codes; for example GNU
  4. 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.
  5. For the shell’s purposes, a command which exits with a zero exit status has succeeded.

This system call facilitates passing the exit status code back to the parent, which can retrieve this value using the wait system call. To execute a follow-on command after sucess, we use the && operator: SomeCommand.exe && ECHO SomeCommand.exe succeeded! The echo statement writes that return code. http://1pxcare.com/batch-file/bat-file-check-return-code.html up vote 489 down vote favorite 99 I am running a program and want to see what its return code is (since it returns different codes based on different errors).
