Hi Tiglath,
There is no option to randomly delete.  You need to specify residue numbers or names, or use selection, e.g.

delete :246,300-312,43
delete #0:212.A
delete sel

... where "sel" in the latter means the current selection.  There are many more examples of command-line atom specification in this page:

I hope this helps,
