This might help you:
Code: Select all
@echo off
setlocal
set "logFile=test.txt"
set "outFile=out.txt"
(
for /F "tokens=* delims=" %%a in ('findstr /C:"fatal error" "%logFile%"') do echo(%%a
) > "%outFile%"
endlocal
goto :eof

Edit: Corrected the code.

Sorry, i have forgotten to use /C:, so i added it to the code above.
Without the C option findstr outputs all lines with "fatal" or "error", the space then is treated as a separator.
When using the C option findstr writes all lines with "fatal error" as one search string to the output.
Btw: If you want to ignore if characters are lower case or upper case, you might use the option /I.
