execve: disallow argc == 0 2022-02-10T20:21:59+00:00 Kyle Evans kevans@FreeBSD.org 2022-01-25T22:47:23+00:00 7393eedb039acb7890da9743a8e8322827820b2c The manpage has contained the following verbiage on the matter for just under 31 years: "At least one argument must be present in the array" Previous to this version, it had been prefaced with the weakening phrase "By convention."
