Hi, I have a batch program which does some functionality and writes a log file. This log file will also contain errors if any. But the program always ends with an error level of 0. I have added the following line findstr /c:Error "%BXT_LOG_FILE%" to find any lines with the word error. This is working fine and my sysout shows perfectly all error messages. Now I want a condition to check if findstr returned error messages then set errorlevel as 1 else 0 and write this errorlevel to the same log file how can i do this? Regards, Jan

DOS doesn't have findstr, so I presume you meant to say XP. Findstr returns 1 when it cannot find the string, and 0 when it does. This is the reverse of what you're asking, so you could do this: if errorlevel 1 ( echo No errors! ) else ( echo Some errors were present. ) If you really want to reverse the errorlevels: if errorlevel 1 (cmd /c exit 0) else (cmd /c exit 1)
