Extracting data of wads via command line

Hello doom editing experts!

I would like to extract sprites as png's and sound files as wav's via the command line from a wad. So what you can do with XWE or SLADE, but without using a graphical interface, but from the command line. Is there a tool out there which allows me to do this?

You could give WadExt a try.

Deutex! Although it can't export it to png, only bmp, gif and ppm. But it can export sounds to wav though.

thank you a lot! this is exactly what I looked for. Though I should not have said that I explicitly need png, but a normal picture format, bmp is just as fine :).
