For safety reasons each script must return non zero value if error detected (to enable 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.

add simple error handling to the script in a .cmd file? For example, if I have: RENAME C:\MyDir\MyFile.txt MyFilexxx.txt And I get an error http://www.mandrilo.com/index.php/mini-how-to-archive/149-windows-dos-batch-programming-error-handling like "The system cannot 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 https://social.technet.microsoft.com/Forums/scriptcenter/en-US/eca202a4-c8f3-40b6-a8b4-f4dad9682d55/add-simple-error-handling-to-cmd-file?forum=ITCG %ERRORLEVEL% == 0 GOTO END REM here 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.

and Signals and Traps (Oh My!) - Part 1 by William Shotts, Jr. In this lesson, we're going to look at handling errors during the execution of your http://linuxcommand.org/wss0150.php scripts. The difference between a good program and a poor one is http://www.freepascal.org/docs-html/user/userse70.html often measured in terms of the program's robustness. That is, the program's ability to handle situations in which something goes wrong. Exit status As you recall from previous lessons, every well-written program returns an exit status when it finishes. If a program finishes successfully, the exit status will be command line zero. If the exit status is anything other than zero, then the program failed in some way. It is very important to check the exit status of programs you call in your scripts. It is also important that your scripts return a meaningful exit status when they finish. I once had a Unix system administrator who wrote a script for command line arguments a production system containing the following 2 lines of code: # Example of a really bad idea cd $some_directory rm * Why is this such a bad way of doing it? It's not, if nothing goes wrong. The two lines change the working directory to the name contained in $some_directory and delete the files in that directory. That's the intended behavior. But what happens if the directory named in $some_directory doesn't exist? In that case, the cd command will fail and the script executes the rm command on the current working directory. Not the intended behavior! By the way, my hapless system administrator's script suffered this very failure and it destroyed a large portion of an important production system. Don't let this happen to you! The problem with the script was that it did not check the exit status of the cd command before proceeding with the rm command. Checking the exit status There are several ways you can get and respond to the exit status of a program. First, you can examine the contents of the $? environment vari
source file to compile from "arg1" into "arg2" You can specify only one source file on the command line. The last one will be compiled, others will be ignored. This may indicate that you forgot a '-' sign. Warning: DEF file can be created only for OS/2 This option can only be specified when you're compiling for OS/2. Error: nested response files are not supported You cannot nest response files with the @file command line option. Fatal: No source file name in command line The compiler expects a source file name on the command line. Note: No option inside arg1 config file The compiler didn't find any option in that config file. Error: Illegal parameter: arg1 You specified an unknown option. Hint: -? writes help pages When an unknown option is given, this message is diplayed. Fatal: Too many config files nested You can only nest up to 16 config files. Fatal: Unable to open file arg1 The option file cannot be found. Reading further options from arg1 Displayed when you have notes turned on, and the compiler switches to another options file. Warning: Target is already set to: arg1 Displayed if more than one -T option is specified. Warning: Shared libs not supported on DOS platform, reverting to static If you specify -CD for the dos platform, this message is displayed. The compiler supports only static libraries under dos. Fatal: In options file arg1 at line arg2 too many #IF(N)DEFs encountered The #IF(N)DEF statements in the options file are not balanced with the #ENDIF statements. Fatal: In options file arg1 at line arg2 unexpected #ENDIFs encountered The #IF(N)DEF statements in the options file are not balanced with the #ENDIF statements. Fatal: Open conditional at the end of the options file The #IF(N)DEF statements in the options file are not balanced with the #ENDIF statements. Warning: Debug information generation is not supported by this executable It is possible to have a compiler executable that doesn't support the generation of debugging info. If you use such an executable with the -g switch, this warning will be displayed. Hint: Try recompiling with -dGDB It is possible to have a compiler executable that doesn't
