command line for eraser - pseudorandom data x passes.

[gogoland2002]

hi there,
i'm using a filemanager in which i can edit my own buttons (directory opus) and now would like to have an "erase"-button, for x-pass pseudorandom-data erasing.
can someone please tell me the commandline i would have to use for this?

thank you for your time!

just wanna clarify:

i wanna select a couple of files just like in the explorer and when clicking on the "delete"-button they should get erased per x-pass pseudorandam-date-erase.
thx
