Well, lots

	By studying the differential CPU usage between "echo" and "echo hello"
one can deduce the CPU time required for the shell to set up arguments. A -q
option would facilitate this study.
	It is an idea command name with which to practice touch typing.
	It is a command which is easy to learn.
	It exercises the disk.
	It is a firm base for an April 1 ruse.
