Bat file for searching

[Magnum]

It took around 4.5 seconds to find 2 identical search.bat files in different directories using s*.bat as the search pattern.


A future improvement is search.bat s*.asm without the search pattern being hard coded into the bat file.

I recall using %1.

:: Search.bat Dave Benham,mousio,

cls
@echo off
echo.
echo Timer has started.
echo.
call :StartTimer
::
:: Add your script functionality here

@echo off
setlocal disableDelayedExpansion
set "searchRoot=."
set "fileMask=s*.bat"

set "prior=noMatch"
for /f "tokens=1,2 delims=?" %%A in (
  '(for /r "%searchRoot%" %%F in ("%fileMask%"^) do @echo %%~zF:%%~nxF?%%~fF^)^|sort'
) do (
  set "current=%%A"
  setlocal enableDelayedExpansion
  if !prior! equ !current! (
    if defined priorFile (
      echo(
      echo !priorFile!
    )
    endlocal
    echo %%B
    set "priorFile="
  ) else (
    endlocal
    set "prior=%%A"
    set "priorFile=%%B"
  )
)

call :StopTimer
call :DisplayTimerResult
pause
goto :EOF

:StartTimer
:: Store start time

A future improvement is search.bat s*.asm without the search pattern being hard coded into the bat file.

@echo off
echo *** Using first char and extension of %1 ***
set spat=%~n1
set spat=%spat:~0,1%*%~x1
echo.
echo %spat%
echo.
pause

hi Andy,

i often start batch files that use parameters by testing to see that the user entered a parameter

Code Select Expand

@echo off
if "x%1"=="x" goto ascusage
if exist %1.asm goto ascasm
:ascusage
echo Usage: asc asmfile
echo "asmfile" = asmfile.asm
goto batchexit
:ascasm
;
;
in that example, i make sure there is a file, otherwise i show a "usage" message and exit

but, in your case,

Code Select Expand

if "x%1"=="x" goto ascusage
is the main line of interest
"x%1"=="x" would evaluate true if %1 is a null string

that avoids a bunch of error type messages if you plod through the batch file with no parameter

Thanks gentlemen.

I will look it over.
