This is a very cool solution! A question I have is what art intended for
the following cases:
rm file1 file2
rm file*
rm file.???
My bet is that the first case, he'd not want interactive rm, but in the
second and third
he would. Am I correct in my supposition that wild cards are expanded
prior to
invocation of the shell function? That would make this desire
impossible, wouldn't it?
Anyone have any idea how we might expand this solution to accommodate
non-wild card
multi parameter invocations or rm?
