Solve : How Use Errorlevel Handler? |
|
Answer» I have scripts which has many DOS copy / xcopy / move statements. I do not want to code if %ERRORLEVEL% after each statement which is completely inefficient, anyone have thoughts for the best way in handling this? I do not want to code if %ERRORLEVEL% after each statement which is completely inefficient Do you want to abort the script if a copy statement threw an error ? What do you mean "inefficient"? I want it to continue onward, eg., execute copy1 then call the errorhandler, then return to execute copy2,..... copy1 call errorhandler # will always return to the next stmt whether there is an error or not copy2 call errohandler # will always return to the next stmt whether there is an error or not ..... copyN So the errorhandler will write a message to a log file and then return? What message? Will the errorhandler do ANYTHING else? Why do you think you need to "call" the error handler? You see, I don't understand why you think this... Code: [SELECT]copy command1 call :errorhandler %errorlevel% copy command 2 call :errorhandler %errorlevel% ... copy command N call :errorhandler %errorlevel% goto end :errorhandler if %1 gtr 0 echo %date% %time% Copy error happened! >> error.log goto :eof :end echo script finished is more efficient than this: Code: [Select]copy command1 if %errorlevel% gtr 0 echo %date% %time% Copy error happened! >> error.log copy command 2 if %errorlevel% gtr 0 echo %date% %time% Copy error happened! >> error.log ... copy command N if %errorlevel% gtr 0 echo %date% %time% Copy error happened! >> error.log echo script finished When running a batch script that has copy | xcopy | move, it is possible to be unaware of an error not until someone tells you they are missing a file. You are correct that the error handler probably is not more efficient especially if I just want to OUTPUT that there was an error encountered since I am not zeroing in on a particular error code. It's always good to get others ideas.... Thanks Salmon Trust. I do not recall, what would the errorlevel be for the following: copy path1\file path2\file >> /tmp/log.txt 2>&1 if %errorlevel% gtr 0 echo %date% %time% Copy error happened! >> error.log the ">>" is just to capture the resultant output from the copy | move | xcopy command... if the copy failed, but the ">>" was successful, what would the errorlevel be set to? if the copy was successful, but the ">>" to a file failed, what would errorlevel be set to? |
