we have discussed an alternative of "stdin",
(see a different thread "stdin ?")
here is another application of "stdin",
poor man's "sed" - well sort of:
コード:

@for /f "delims=" %%i in ('more') do @set FOO=%%~i & echo !FOO:%~1=%~2!


sample run (1) self morphing
コード:

C:\> type sed.bat | sed.bat FOO BAR

@for /f "delims=" %%i in ('more') do @set BAR=%%~i & echo %1=%2


sample run (2) abs --> rel paths
コード:

C:\Program Files>dir/b/s *.exe | sed.bat "C:\Program Files" .

.\Common Files\Microsoft Shared\MSInfo\msinfo32.exe

...

.\FreeAmp\Tools\MakeTheme.exe


known bug - blank lines get deleted.
any fix?

'findstr' fixes the blank-line missing bug:
コード:

@echo off

setlocal

for /f "tokens=1* delims=:" %%i in ('findstr /n "^"') do (

    if "%%j"=="" (

        echo.

    ) else (

        set FOO=%%~j

        echo !FOO:%~1=%~2!

    )

)

endlocal

goto :eof


however special characters (&!) produce side effects as you can see by:
コード:

C:\> type sed.bat | sed.bat FOO BAR

...

    ) else (

        set BAR=%%~j

        echo    set BAR=%%~j

    )

...

sigh...
