Powershell Script Error Handling

Join them; it only takes a minute: Sign up Batch Programming, Error Handling, and Start Command up vote 6 down expect script error handling vote favorite I am just starting to learn how to script. I'm trying to understand how the system handles Error Levels and how they can be used in error handling. I know there is a difference between the environment variable %ERRORLEVEL% and the Error Level of the system. If I understand this correctly, then the If ERRORLEVEL 1 code would check the environment variable before it checks the error batch script error handling level of the previous command. So, in my program I am trying to interface a startup/stop script that will start/stop all scripts of a given machine (for testing I'm just using one application notepad.exe as an example). I have two wrapper scripts that will either start up or stop the applications by passing arguments to the independent script. If there is an error in the independent script, it will set the errorlevel using the EXIT /B n command. Once control is returned to the calling script, it will go to an error handling script if the exit status is non-zero. At first I was setting the %ERRORLEVEL% to zero manually and then testing for an error after a START or TASKKILL command. But then I read that clearing %ERRORLEVEL% with SET ERRORLEVEL= is a better method. My issue comes in when I try to start the app with START "" notepad.exe Whenever I test the errorlevel after this command it is always greater than or equal to 1 unless I use SET ERRORLEVEL=0 before I run the start command. I have inserted the code for the four scripts below. Any insight and advice would be greatly appreciated. appstart.bat: @echo off :: Script for applicat

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 http://www.mandrilo.com/index.php/mini-how-to-archive/149-windows-dos-batch-programming-error-handling 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.

Contact Failed Mail Donate Errorlevels The correct name for errorlevels would be return codes. But since the DOS command to determine the return code is IF ERRORLEVEL, most people use the name errorlevel. Errorlevels are not a standard feature of every command. A certain errorlevel may mean anything the programmer wanted it to. Most programmers agree that an errorlevel 0 means the command executed successfully, and an errorlevel 1 or higher usually spells trouble. But there are many exceptions to this general rule. IF ERRORLEVEL construction has one strange feature, that can be used to our advantage: it returns TRUE if the return code was equal to or higher than the specified errorlevel. This means most of the time we only need to check IF ERRORLEVEL 1 ... and this will return TRUE for every non-zero return code. In Windows NT4/2000/XP this may sometimes fail, since some executables return negative numbers for errorlevels! However, this can be fixed by using the following code to check for non-zero return codes: IF %ERROR
