Please help me remove a volume in shell (terminal)

[Metal Storm]

I canot delete some volumes i made other then in the terminal because I had formated them special for a dual boot that I am no longer going to do. I need terminal shell script to delete a volume. I looked it up online and in my linux books, but the syntex I use must be wrong. Please provide me with an example of the correct syntex to delete a volume thank you. I have worked with linux some, never mac. Thanks for your time.

This is as far as I can get and there is a syntax error.

Sudo diskutil eraseVolume disk0s3

or

sudo diskutil eraseVolume [MS-DOS FAT32] <disk0s3>
