Profman, I assume you are asking what the switches are for the wipe command. If so, here is the syntax:
wipe: wipe [-dN] [-pXX...] [-s] [-dod]
-dN wipe disk N (1-based, default=1)
-pXX... hex pattern, 1 or more bytes (default=00)
-s stamp drive with MBR showing not bootable when done
-dod write a pattern, its inverse, then random bytes
-quick wipe only the first and last track of the specified disk
