And if the first command is ``silent'':

	(gdb) b main
	Breakpoint 1 at 0x8048822: file twofloats.c, line 19.
	(gdb) commands 1
	Type commands for when breakpoint 1 is hit, one per line.
	End with a line saying just "end".
	>silent
	>list
	>continue
	>end
	(gdb) run

the ``breakpoint'' message is supressed.
