exit dos script error Ducktown, Tennessee

Most programs rarely document every possible return code, so I’d rather explicity check for non-zero with the NEQ 0 style than assuming return codes will be 1 or greater on error. At the end of your subroutine, you can jump to the end of the batch file (so that execution falls off the end) by doing a goto :eof. Calling a batch file without using call traditionally results in the caller terminating as soon as the callee does; however it seems this doesn't happen anymore (just realized I made a For example, an environment variable with a standard name can store the location that a particular computer system uses to store user profile this may vary from one computer system to

In that case we can use generic checks for failures like this: IF EXIST %outfile% (DEL /F %outfile%) CALL some_script.bat -o %outfile% IF NOT EXIST %outfile% (ECHO ERROR & EXIT /b)

SomeCommand.exe || GOTO :EOF Tips and Tricks for Return Codes I recommend sticking to zero for success and return codes that are positive values for DOS batch files. You can use start /wait if you want to wait on one, though. use EXIT /B < exitcodes > at the end of the batch file to return custom return codes. If quitting CMD.EXE, sets the process exit code with that number.That's exactly what I was looking for!Thanks a lot!Works like a charm!Gabor Logged billrich Guest

The goto :eof trick becomes even more handy when you start playing with batch file subroutines. Batch files are a great place to see lots of examples of stuff that was done wrong ages ago, but which can't be fixed due to backward compatibility issues.

I also recommend documenting your possible return codes with easy to read SET statements at the top of your script file, like this: SET /A ERROR_HELP_SCREEN=1 SET /A ERROR_FILE_NOT_FOUND=2 Note that Not the answer you're looking for? Before posting on our computer help forum, you must register. This is logically equivalent to a batch file recursively calling itself, except that execution begins at the specified label instead of the first line of the file. (It's as if a

Errors in the syntax of constructs like if exists or for will cause the shell to stop executing a script.

A very simple way to halt on error is to use the EXIT command with the /B switch (to exit the current batch script context, and not the command prompt process).

EXIT without an ExitCode acts the same as goto:eof and will not alter the %ERRORLEVEL% You should never attempt to directly write to the %ERRORLEVEL% variable, (SET errorlevel...) instead use the SET /A ERROR_HELP_SCREEN=1 SET /A ERROR_FILE_NOT_FOUND=2 SET /A ERROR_FILE_READ_ONLY=4 SET /A ERROR_UNKNOWN=8 This gives me the flexibility to bitwise OR multiple error numbers together if I want to record numerous problems What is the most expensive item I could buy with £50? wscript.quit will return custom return codes from the script Example: vb script for Copying File to a Folder dim filesys set filesys=CreateObject("Scripting.FileSystemObject") If filesys.FileExists("c:\samplefile.txt") Then filesys.CopyFile "c:\samplefile.txt", "C:\manageengine"
