QUESTION NO: 23
Your /etc/syslog.conf file contains the line:
*.alert;kern.err;daemon.notice @operator
To which destination are messages sent?
A. The user named operator.
B. The host named operator.
C. The /var/log/operator file.
D. All members of the group operator.

题目提供的答案居然是A, 如果真是A的话,还要这个"@"干什么?

它的作用相当于"指向"指定的用户,这是系统的对指向的特定符号.
