    最佳解答

    1.(a)they are automatically logged out

    這一題有點奇怪,單人模式沒有網路功能,一進入後

    其身分就是root,他可以切換使用者。沒有登入問題

    2. (d)mail bob@foo.bar.org < /var/log/dmesg

    3.lprm

    4.(d)It stores a list of all directories which contain manpages.

    5./etc/motd

    6.(c)This is a full backup

    7(b)a special IP-address which addresses all hosts on a particular network

    sorry,將第五題答案為/etc/issue

    /etc/motd是在成功登入後顯示(在執行login shell之前顯示)
