Multiple instances of a RegEx string in FINDSTR

I am looking for a way in a Windows batch file to find if a file contains the word Shutdown a given number of times.

I have tried this using FINDSTR:

 FINDSTR /r .*Shutdown.*{5} file.txt

This doesn't seem to work, but if I remove the {5} it executes successfully.

Also I would eventually like the 5 to be a variable, presumably this is possible with some sort of dynamic command?

Thanks

Solution 
  • .*Shutdown.*Shutdown.*Shutdown.*Shutdown.*Shutdown.*

    would seem to be the only way for FINDSTR

    srsly.

    Test batch:

    @ECHO OFF
SETLOCAL
FOR /f "delims=" %%i IN (f5shutdown.txt) DO (
 ECHO %%i|FINDSTR /r .*Shutdown.*Shutdown.*Shutdown.*Shutdown.*Shutdown.* >NUL
 IF ERRORLEVEL 1 ECHO FAILED IN "%%i"
 IF NOT ERRORLEVEL 1 ECHO FOUND  IN "%%i"
)

GOTO :eof

    Test textfile in f5shutdown.txt

    Shutdown
Shutdown Shutdown
Shutdown Shutdown Shutdown Shutdown
Shutdown Shutdown Shutdown Shutdown Shutdown
Shutdown already !Shutdown Shutdown Shutdown Shutdown now
You should now Shutdown Shutdown Shutdown Shutdown Shutdown
ShutdownShutdownShutdownShutdownShutdown
OK, don't shutdown then...

    Result:

    FAILED IN "Shutdown"
FAILED IN "Shutdown Shutdown"
FAILED IN "Shutdown Shutdown Shutdown Shutdown"
FOUND  IN "Shutdown Shutdown Shutdown Shutdown Shutdown"
FOUND  IN "Shutdown already !Shutdown Shutdown Shutdown Shutdown now"
FOUND  IN "You should now Shutdown Shutdown Shutdown Shutdown Shutdown"
FOUND  IN "ShutdownShutdownShutdownShutdownShutdown"
FAILED IN "OK, don't shutdown then..."

    Works for me (W7)

    Ah - perhaps you meant "occurs on 5 (or whatever) lines or "occurs 5 times in the file"...

    @ECHO OFF
SETLOCAL
FOR /f "delims=" %%i IN (f5shutdown.txt) DO (
 ECHO %%i|FINDSTR /r .*Shutdown.*Shutdown.*Shutdown.*Shutdown.*Shutdown.* >NUL
 IF ERRORLEVEL 1 ECHO FAILED IN "%%i"
 IF NOT ERRORLEVEL 1 ECHO FOUND  IN "%%i"
)

:: For 'shutdown' on n different lines: (assuming case-insensitive)
FOR /f %%i IN ('FIND /i /c "shutdown" ^<f5shutdown.txt') DO SET shutdowns=%%i
ECHO Second method: %shutdowns% lines found with "Shutdown"

:: For 'shutdown' occurrences (assuming case-insensitive)
SET /a shutdowns=0
FOR /f "delims=" %%i IN (f5shutdown.txt) DO (
 SET line=%%i
 CALL :findem
)
ECHO Third method found "Shutdown" %shutdowns% times
GOTO :eof

:findem
SET line=%line:"=%
SET after=%line:*shutdown=%
IF NOT DEFINED after SET /a shutdowns+=1&GOTO :EOF 
if NOT "%line%"=="%after%" SET "line=%after%"&SET /a shutdowns+=1&GOTO findem
GOTO :eof

    (I added an extra non-shutdown-containing line for the test. Found 8 lines and 28 occurrences)
