I'm making a script and I want to take an existing partition and clear it quickly. Rather than using rm I thought there might be a command-line way of formatting or initializing a partition, but I couldn't find it.

I don't want to trash my whole disk...will this also work on /dev/disk/ata/0/master/3 even though it doesn't seem to have a raw subdir if I try autocomplete in a Terminal? –  Kev Apr 7 '13 at 21:36
    
Turns out it will. Thanks! –  Kev Apr 14 '13 at 13:44
