in reply to dos2unix line endings on Windows

You clobber the caller's PERLIO. Fixed: 

@echo off

if "%1"=="" goto usage

setlocal
set PERLIO=perlio
for /r %1 %%X in (*.*) do (
    perl -pi.bak -e "s/\r\n/\n/g" "%%X"
    del "%%X.bak"
)
goto bye

:usage
echo.
echo  USAGE: %0 directory
echo.

:bye

    I usually try to return things to their original state, that's why I did it. I think when you run this file in an open CMD session, the PERLIO will remain set after batch file execution. but you may not want it in the consequent Perl one liners.

      Correct. So if it was PERLIO=foo before your batch file ran, you changed it to PERLIO=.

      Except it didn't return it to its original state. The change I made returns it to its original state.
