Dos On Error Goto
them fails, I want to exit the whole program. For example: @echo off type foo.txt 2>> error.txt >> success.txt mkdir bob If the file foo.txt isn't found then I want the stderr message appended to the error.txt file, else the contents of foo.txt is appended to success.txt. Basically, if the type command returns a stderr then I want the batch file to exit and not create a new directory. How can you tell if an error occurred
Dos Commands
and decide if you need to continue to the next command or not? ms-dos stderr share|improve this question asked Jul 21 '10 at 20:33 Notorious2tall 92041125 I added the code IF NOT ERRORLEVEL 0 EXIT /B echo %errorlevel% before the mkdir bob command, but regardless of the value of ERRORLEVEL (i.e. 0 or 1) the directory is still created. So basically, ERRORLEVEL is being set with a different value whether the type command finds the file or not, but the program is not exiting. Thoughts? –Notorious2tall Jul 21 '10 at 21:07 add a comment| 1 Answer 1 active oldest votes up vote 10 down vote use ERRORLEVEL to check the exit code of the previous command: if ERRORLEVEL 1 exit /b EDIT: documentation says "condition is true if the exit code of the last command is EQUAL or GREATER than X" (you can check this with if /?). aside from this, you could also check if the file exists with if exist foo.txt echo yada yada to execute multple commands if the condition is true: if ERRORLEVEL 1 ( echo error in previous command & exit /b ) or if ERRORLEVEL 1 ( echo error in previous command exit /b ) share|improve this answer edited Apr 2 '14 at 16:26 danio 4,04142043 answered Jul 21 '10 at 20:39 akira 4,7601828 add a comment| Your Answer

I've been Googling a bit for a general error handling approach and can't find anything really useful. Basically if any thing goes wrong I http://stackoverflow.com/questions/1164049/batch-files-error-handling want to stop and print out what went wrong.

The error branch will fire if the last command in the success branch raises an error. yourCommand && ( someCommandThatMayFail ) || ( echo This will fire if yourCommand or someCommandThatMayFail raises an error ) The fix is to insert a harmless command that is guaranteed to succeed at the end of the success branch. I like to use (call ), which does nothing except set the ERRORLEVEL to 0. There is a corollary (call) that does nothing except set the ERRORLEVEL to 1. yourCommand

But my bat stops at cmd1. How can I avoid this? Update for clarity - these are not other .bat files, they are exe commands. Hopefully I don't have to build a tree of .bat files just to achieve this. windows command-line batch-file share|improve this question edited Jan 3 '13 at 22:38 asked Jan 3 '13 at 22:16 ConfusedNoob 2721616 You should be able to start the command using cmd /C. –Oliver Salzburg♦ Jan 3 '13 at 22:49 1 You need to show a specific code example of what is not working. Batch files normally do not terminate automatically if a command fails with an error. Batch files do terminate if there is a syntax error. If your code is exiting upon an exe error, then there must be logic in your code that is causing that behavior. –dbenham Jan 4 '13 at 14:59 add a comment| 3 Answers 3 active oldest votes up vote 5 down vote Another option is to use the amperstand (&) cmd1 & cmd2 & cmd3 If you use a double, it only carries on if the previous command completes successfully (%ERRORLEVEL%==0) cmd1 && cmd2 && cmd3 share|improve this answer answered Jan 3 '13 at 22:35 Canadian Luke 15.6k2374124 Can I do this when passing args also?
