Another example of this is given farther on. (See this website's Batch File Tutorial for information on writing batch files.) What do Exit Codes Look Like? SomeCommand.exe || EXIT /B 1 A simliar technique uses the implicit GOTO label called :EOF (End-Of-File). This documentation is archived and is not being maintained. Exit
if you use Code: [Select]if errorlevel gtr 0 exit /b  anything over errorleve==1 would exit with exit code 1FB Logged Next time google it. I have hundreds of friends. A windowed application will run in the background, and control will return immediately to the command prompt (most likely with an ErrorLevel of zero to indicate that the process was created CHOICE /C:123<- /N > NUL IF ERRORLEVEL 4 GOTO END IF ERRORLEVEL 3 GOTO DATABASE IF ERRORLEVEL 2 GOTO SPREADSHEET IF ERRORLEVEL 1 GOTO WORD-PROCESSOR GOTO END :WORD-PROCESSOR (start word processor
This type of compare ("%errorlevel%=="0") becomes dubious at best.B.bat can use the exit statement to pass a return code (errorlevel) back to a.bat.QuoteQuits the CMD.EXE program (command interpreter) or the current if( !CreateProcess( NULL, // No module name (use command line) (LPTSTR)(strCmd.GetString()), // Command line NULL, // Process handle not inheritable NULL, // Thread handle not inheritable FALSE, // Set handle inheritance Be aware that other DOSes may use different codes or not generate a code other than `0' regardless of an operation's results.
ECHO 1. Returns the error code of the most recently used command. share|improve this answer answered Mar 26 '10 at 8:16 Andras Vass 9,4162341 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Dos Error Code 255 XCOPY, for instance can fail with errorlevels 1 to 5.
In that case, they might conceivably have available a huge list of possible results. Dos Prompt Commands You would have specific instructions for each possible outcome that the program might present upon its completion. Checking Return Codes In Your Script Commands The environmental variable %ERRORLEVEL% contains the return code of the last executed program or script. http://steve-jansen.github.io/guides/windows-batch-scripting/part-3-return-codes.html So "IF ERRORLEVEL 2 GOTO PROBLEM" actually says if the exit code is level `2' or higher, the batch file is to branch to the "PROBLEM" section.
So i created a little bash script to take care of this. Error Code 1 For Command Cmd With Args if /B is specified, sets ERRORLEVEL that number. You have to code for halting on error. Word Processor ECHO 2.
Indicates that the file can not be found in specified location.3The system cannot find the path specified. original site Once they are known, you may write much smarter batch files to take advantage of them. Dos Command Exit Code Happened when checking %ERRORLEVEL% in a cmd file. Dos Error Code 9009 This possibility would be represented by the case where a batch file programmer has made 254 choices available - an unlikely situation. (Note that CHOICE's Exit Code `0' represents an interruption
Hi, I'm Steve. If quitting CMD.EXE, sets the process exit code with that number. [Brought to my attention by Maor Conforti. It is used to search for a given text string. http://thewebparrots.com/error-code/dns-323-error-code-114.php If the word is not found, the batch file is directed to end.
Because these codes are mainly meant to show errors, they are known as "Error Codes" or "Error Levels". Dos Batch Return Code A very helpful feature is the built-in DOS commands like ECHO, IF, and SET will preserve the existing value of %ERRORLEVEL%. Error can indicate a bug in the executed software that causes stack overflow, leading to abnormal termination of the software.3762507597

What matters is did the script work or not? SET /A ERROR_HELP_SCREEN=1 SET /A ERROR_FILE_NOT_FOUND=2 SET /A ERROR_FILE_READ_ONLY=4 SET /A ERROR_UNKNOWN=8 This gives me the flexibility to bitwise OR multiple error numbers together if I want to record numerous problems I was thinking more along the line where b.bat would abort early based on some condition:b.batCode: [Select]if not exist c:\file.ext exit 7
if not defined userprofile exit 9
a.bat Unix Error Code Instead of using the console-based C++ launcher mentioned elsewhere, though, a simpler alternative is to start a windowed application using the command prompt's START /WAIT command.

How does an exponent work when it's less than one? Conversely, if the file did not contain the string, a different operation might be done. Do Programs other than DOS Commands Give Exit Codes? Thus, tests are done in descending order. (Note that there is a way to do the tests in ascending order but it means much longer lines of code.
