And one last thing, I'm assuming your umask is probably 022. When chmod
doesn't have the u, g, o, or a qualifies, then it uses the umask to mask
the permission bits as appropriate so the command can be simplified to
the following:
chmod -R =3DrwX .

I sense much NT in you.
NT leads to Bluescreen.
Bluescreen leads to downtime.
Downtime leads to suffering.
NT is the path to the darkside.
Powerful Unix is.
