RDiff.exe is supposed to Return %ERRORLEVEL%

RDiff.exe is supposed to Return %ERRORLEVEL% if it does not prepare a signature properly.
What I noticed is that if the Basis file changes in between creation of Signature it just aborts operation and produces an incomplete signature file.
Problem is that there is no Error indicator to catch this. How to trap this ?

Hi Allan,

To read the exit code of the last executed command in a Windows Batch file is to query the ERRORLEVEL.
Since Windows NT this has been made easier by using the %ERRORLEVEL% environment variable.

This little snippet shows the usage to get a programs exit code.
echo Last code was %ERRORLEVEL%

Open in new window

In this case it should show 0, as no error will be likely.
You can do a simple IF, ELSE test and act accordingly in the event of non-success.

Hope this helps

Try something like this and see if it helps, you can trap for failure of  RDIFF as well as ERRORLEVEL, not sure if this will work or not, can't test here.

RDIFF <parms> || (
    ECHO Errors running RDIFF
    SET RDIFFerr=Y
) && (
        ECHO Error %ERRORLEVEL% running RDIFF
        SET RDIFFerr=Y
    ) ELSE (
    SET RDIFFerr=N

IF "%RDIFFerr%" EQU "N" (
    REM Continue with logic for successful RDIFF

Open in new window
