This is generally a bad idea, though, as any user who gets access to an account that run commands through sudo without a password may be able to compromise the system.
Also, sudo should remember your password for a period of time. If this is timing out too soon for your tastes, you can increase the timeout by following instructions here: http://forums.macosxhints.com/showthread.php?t=83344

使用 /etc/sudoers 中的 NOPASSWD 选项。
不过，这通常是一个坏主意，因为任何在没有密码的情况下访问通过 sudo 运行命令的帐户的用户都可能会破坏系统。
另外，sudo 应该在一段时间内记住您的密码。 如果根据您的喜好，超时时间过早，您可以按照此处的说明增加超时时间： http://forums.macosxhints.com/showthread.php?t=83344
Use the NOPASSWD option in /etc/sudoers.

man sudoers是你的朋友。 它解释了有关NOPASSWD和 sudoers 文件的所有内容，您应该使用visudo编辑该文件。man sudoersis your friend. It explains all aboutNOPASSWDand the sudoers file, which you should edit withvisudo.
