Batch file moves to location in argument

Question

Thanks to rojo the batch file below will check for illegal characters, replace them with a dash, search subdirectories and require a location argument, but when it's run it takes you to the directory you specify in the argument. I want to stay in drive/folder the batch file is run from. (ex: rename.bat c:\test, this will take you to c:\test after batch file runs)

@@echo off
IF "%~1"=="" goto Continue 
pushd %1
setlocal enabledelayedexpansion

for /r %%I in (*) do (
    set "file=%%~nxI"
    if "!file:~0,1!"=="~" (
        set "file=-!file:~1!"
    )
    for %%d in (# %%) do (
        if not "!file!"=="!file:%%d=!" (
            set "file=!file:%%d=-!"
        )
    )
    if not "!file!"=="%%~nxI" (
        echo %%~fI -^> !file!
        ren "%%~fI" "!file!"
    )
)
Exit /B
:Continue

Answer 1

At the end of your FOR /R loop, add POPD to "undo" the directory change performed by the respective PUSHD command.

setlocal enabledelayedexpansion
pushd %1

for /r %%I in (*) do (
...
)

REM Revert back to the original directory.
POPD
ENDLOCAL

Exit /B
