linux上机考试试题及答案

1. chmod 464 ~/.bash_historyhistory -whistory -c

2. umask 112 (注：777 - 654)

3. chmod 744 /root

4. mkdir ~/dir1/0102

5. touch /root/file1

6. chmod 774 /root/file1

7. umaskcat .bash_historyls -ld $HOMEls -l $HOME

8. useradd stu0102

9. passwd stu0102

10. su stu0102(或exit；然后重新登陆)

11. vi ~/infinite...(输入指定内容)chmod a+x ~/infinite~/infinite &

12. ps -fcate infinite

13. ps aux|grep 'infinite'|grep -v 'grep'得到pid然后，kill -9 pid(或者，kill -9 `ps aux|grep -v grep|awk '{print $2}'` )

14. fdisk /dev/sda（root执行，这里以/dev/sda示范）m看帮助，n新建，p主分区，L查看文件系统类型代号列表；创建100M大小主分区：n->p->enter->+100M

15. mkfs.ext3 /dev/sda?(fdisk -l /dev/sda查看分区次序列号？)

16. mount /dev/sda3 /home/classnumber

17. fdisk -ldf -Th

都是些基础知识，自己试试吧。因为我也没有测试不能保证一定没有问题！
