Cmd Error Handling
BlogMoji OrgonitiChemTrail Photo BlogZnanstveniciUmjetnici Windows DOS batch programming - error handling Goal: execute multiple dos bat scripts, each script can call any number of other programs and every script must break execution if error is detected after each step. For safety reasons each script must return non zero value if error detected (to enable batch script error handling error detection if bat script is executed from other program as separate process). To check if error occured after execution of DOS command or after call of external program use this (tested on Windows XP): IF %ERRORLEVEL% NEQ 0 GOTO ERROR_HANDLER where ERROR_HANDLER is label (jump point) in your bat script which contains error handling part of code. Complete example: copy N files from location A to the B and after each step check for error, if error occured print 'Error' otherwise 'Sucess'. Note: 'exit 1' will cause command prompt to close, to avoid this, remove command 'exit 1': @ECHO OFFREM COPY all copy /Y D:\exe\appserver\release\appserver.exe" D:\AppServerDeployIF %ERRORLEVEL% NEQ 0 GOTO ERROR_HANDLER copy /Y "D:\exe\sokrates_spc\release\sokrates.exe" D:\SPCDeployIF %ERRORLEVEL% NEQ 0 GOTO ERROR_HANDLER copy /Y "D:\tool\AdminTool\release\db_actualize.dll" D:\SPCDeployIF %ERRORLEVEL% NEQ 0 GOTO ERROR_HANDLERecho.echo Sucess!!!GOTO QUIT:ERROR_HANDLERecho.echo Error occured!!!exit 1:QUITecho.

don't make any sense. I'm sure they made perfect sense to me at the time. ;-) Wednesday, October 5, 2011 Common DOS batch file bash error handling error handling mistakes I make I write a decent amount of batch scripts now windows cmd error handling days to automate things on windows server boxes. Unfortunately, I don't do it quite frequently enough to remember all the batch file error handling tutorial crazy syntax of DOS commands. One of these errors is error handling. These are the things I commonly need to deal with. I found this page (and site) very helpful for all DOS related http://www.mandrilo.com/index.php/mini-how-to-archive/149-windows-dos-batch-programming-error-handling stuff: http://www.robvanderwoude.com/errorlevel.php Use "IF %ERRORLEVEL% NEQ 0 SET MYERROR=1" to record whether the previous command resulted in an error code. Alternately, you can check for "IF ERRORLEVEL 1 ..." if you want to look for a specific error level. Be cautious of manipulations with ERRORLEVEL. It's not really an environment variable like other variables. In particular, do NOT ever use "set ERRORLEVEL=5" or similar. It will corrupt any http://armillz.blogspot.com/2011/10/common-dos-batch-file-error-handling.html further use of %ERRORLEVEL% syntax by fixing it at a value. Use "CALL FOO.BAT" instead of just "FOO.BAT" when calling subscripts. Otherwise, when that script completes it will not return to the current script. Use "EXIT /B 1" to return an exit code from your script. If you use "EXIT 1" it will exit the entire command shell, including closing your current window if it's running in one. Consider using SETLOCAL and ENDLOCAL within your script to prevent temporary environment variables from carrying through to outer shells. Below is an example script. :: Sample script with some error handling SETLOCAL SET MYPARAM=%1 if "%MYPARAM%"=="" goto :USAGE CALL .\childscript.bat %MYPARAM% if %ERRORLEVEL% NEQ 0 set MYERROR=1 echo. echo Finished child script. Handling errors now... if %MYERROR%==1 GOTO :ERROR echo It worked! ENDLOCAL set SOME_EXTERNAL_VARIABLE=1 GOTO :EOF :USAGE echo Please provide a command line parameter. EXIT /B 2 :ERROR echo It didn't work, dude. EXIT /B 1 Update: I was wrong about the ERRORLEVEL syntax earlier, so I updated after some testing.

For example, if I have: RENAME C:\MyDir\MyFile.txt MyFilexxx.txt And I get an error like "The system cannot error handling find the file specified.", how do prevent it from executing the rest of the script in the cmd file and instead exit (somewhat) gracefully?Thanks,-Dave Friday, August 21, 2009 12:57 AM Reply | Quote Answers 0 Sign in to vote RENAME C:\MyDir\MyFile.txt MyFilexxx.txt IF NOT %ERRORLEVEL% == 0 GOTO END REM here dos command error goes the rest of the script :END Marked as answer by dgolds Friday, August 21, 2009 3:34 PM Friday, August 21, 2009 5:53 AM Reply | Quote Microsoft is conducting an online survey to understand your opinion of the Technet Web site.
