Creating an alias won't solve Art's problem, which is using the "-i" flag
when rm is passed multiple files, but not using "-i" when only a single
file is specified -- rather, an alias will use "-i" in every case.  One
possible solution is to create a bash function which determines how many
arguments it was passed:

	rm()
	{
	    if [ $# -lt 2 ]
	    then /bin/rm $*
	    else /bin/rm -i $*
	    fi
	}

This works for the majority of cases:

	[mct@ellesmere ~]$ touch foo bar baz
	[mct@ellesmere ~]$ rm foo
	[mct@ellesmere ~]$ rm bar baz
	/bin/rm: remove `bar'? y
	/bin/rm: remove `baz'? y

HTH,
