我在通过 /etc/sudoers 文件将用户添加到 sudoers 列表中时遇到问题。
$ whoami
iain
他们说我疯了！
$ which visudo
/usr/sbin/visudo
$ ls -la /usr/sbin/visudo
---x--x--x 1 root wheel 186768 23 Jun 2009 /usr/sbin/visudo
$ sudo su -
Password:
macbook:~ root# whoami
root
macbook:~ root# visudo
该文件在 vi 中打开：
# this line is the one I added to sudoers
# I gave ALL as access to try and get this to work
# it's the same setting as my account, which works.
%yvonne ALL=(ALL) ALL
我保存了文件。这里显示“未更改”，因为我已经保存过了。
visudo: /etc/sudoers.tmp unchanged
macbook:~ root# logout
以 yvonne 身份登录…
$ sudo su - yvonne
yvonne@87 02/08/2013 19:34 $ whoami
yvonne
尝试通过以下方式运行任何程序sudo：
yvonne@88 02/08/2013 19:34 $ sudo ls

**yvonne is not in the sudoers file. This incident will be reported.**
我很困惑，有人能给我一些帮助或见解，让我可以授予帐户yvonne访问权限sudo吗？我将不胜感激。

%是 sudoers 中的组赋值运算符。我认为您希望该行显示为：
yvonne ALL=(ALL) ALL
