batch find errorlevel
FIND returns an errorlevel 1 if the search string wasn't found (as of MS-DOS 6). IsDev.bat is an example of a batch file depending on this ..., FIND "[ERR" "text.csv" sets ERRORLEVEL to 0 if at least one [ERR is found, and 1 if no [ERR is found. You need a way to invert the logic.
