cat a.txt | tee /root/ha.txt 1>/dev/null

或者把来sh命令来执行:

sudo sh -c “echo \”www\” > /root/a.txt “

ssh -tt my@remote.host sudo ls

意识到问题的严重，通过搜索来到这里。请教博主后来是怎样重构的？做成Component放到components目录下，似乎可行，只是我还不太理解正常情况下components是做什么的。。直接继承AR类放到model目录下？这好像才是“正确”的方式。。

function mytime(){
	$t = microtime(true);
	$d = substr(sprintf('%03d', ($t - intval($t)) * 1000), 0, 3);
	$str = date("Y-m-d H:i:s,$d", $t);
	return $str;
}
