Need help! (cd ../ mkdir tmp)

[TemplarDrake]

Hi guys! First post so be gentle! I am not sure I found the right place, so if I did not please see if you can direct me somewhere I can find the solution!

I am posting for a friend so I don't know all the details. Trying to pack/unpack on Github and for that we need a bat file for Windows.

So far we have:

@echo off
echo Creating temporary storage.
if exist ../tmp/ (del ../tmp) else (cd ../ mkdir tmp)

Everything works but the else-clause gives issues. We tried mkdir ../tmp, but that didn't work neither did cd ../ mkdir tmp.

What we are trying to do is: if ../tmp doesn't exist, create it.

Anyone have an idea?

Code: Select all

md "..\tmp" 2>nul

Another question!

Need to create subdirectories based on file extensions.

FOR %%i IN (.) DO (
ECHO ..\unpacked\%%~xi
)

The above code provides extension with a period. How can I get rid of the period?

Thanks in advance!

Code: Select all

FOR %%i IN (*) DO (
   setlocal enabledelayedexpansion
   set ext=%%~xi
   set ext=!ext:~1!
   ECHO ..\unpacked\!ext!
   endlocal
)

Code: Select all

FOR %%i IN (*) DO (
   setlocal enabledelayedexpansion
   set ext=%%i
   set ext=!ext:~1!
   ECHO ..\unpacked\!ext!
   endlocal
)

…Perhaps %%~xi

Here's a oneliner:

Code: Select all

ForFiles /C "Cmd /C If @IsDir==FALSE If Not Exist ..\unpacked\@Ext MD ..\unpacked\@Ext">Nul

To take it a little further, you could use a similar line to move all files to the respective folder based on their extension:

Code: Select all

ForFiles /C "Cmd /C If @IsDir==FALSE ((If Not Exist ..\unpacked\@Ext MD ..\unpacked\@ext>Nul)&Move /Y @File ..\unpacked\@ext>Nul)"

Give this a shot too:

Code: Select all

for %%a in (.) do for /f "delims=." %%b IN ("%%~xa") DO (
ECHO ..\unpacked\%%b
)
