Linux基础命令操作
作者:互联网
**1、请用命令查出ifconfig命令程序的绝对路径**
**[root@localhost ~]#** *which ifconfig
/usr/sbin/ifconfig*
**2、请用命令展示以下命令哪些是内部命令,哪些是外部命令?(cd \ pwd \ ls \ ifconfig \ du)**
**[root@localhost ~]#** *type cd
cd 是 shell 内嵌 (由此可见该命令cd为内部命令)*
**[root@localhost ~]#** *type pwd
pwd 是 shell 内嵌 (由此可见该命令cd为内部命令)*
**[root@localhost** ~]# *type ls
ls 是 `ls --color=auto' 的别名 (由此可见该命令cd为外部命令)*
**[root@localhost ~]#** *type ifconfig
ifconfig 是 /usr/sbin/ifconfig (由此可见该命令cd为外部命令)*
**[root@localhost ~]#** *type du
du 是 /usr/bin/du (由此可见该命令cd为外部命令)*
**3、请在/下创建目录abc**
**[root@localhost ~]#** *mkdir -pv /abc
mkdir:*
**已创建目录 "/abc" 请在/下创建目录/liangjian/liyunlong/weiheshang/duanpeng**
**[root@localhost abc]#** *mkdir -pv /liangjian/liyunlong/weiheshang/duanpeng
mkdir:已创建目录 "/liangjian"
mkdir: 已创建目录 "/liangjian/liyunlong"
mkdir: 已创建目录 "/liangjian/liyunlong/weiheshang"
mkdir: 已创建目录 "/liangjian/liyunlong/weiheshang/duanpeng"*
**请在/abc下一次创建1000个目录,名字自己拟定。**
**[root@localhost ~]#** *cd /*
**[root@localhost /]#** *cd abc
**[root@localhost abc]#** mkdir jhc{1..1000}*
**[root@localhost abc]#** *ls*
*jhc1 jhc168 jhc237 jhc306 jhc376 jhc445 jhc514 jhc584 jhc653 jhc722 jhc792 jhc861 jhc930jhc10 jhc169 jhc238 jhc307 jhc377 jhc446 jhc515 jhc585 jhc654 jhc723 jhc793 jhc862 jhc931jhc100 jhc17 jhc239 jhc308 jhc378 jhc447 jhc516 jhc586 jhc655 jhc724 jhc794 jhc863 jhc932jhc1000 jhc170 jhc24 jhc309 jhc379 jhc448 jhc517 jhc587 jhc656 jhc725 jhc795 jhc864 jhc933jhc101 jhc171 jhc240 jhc31 jhc38 jhc449 jhc518 jhc588 jhc657 jhc726 jhc796 jhc865 jhc934jhc102 jhc172 jhc241 jhc310 jhc380 jhc45 jhc519 ......*
**4、请用绝对路径方式切换到/liangjian/liyunlong/weiheshang/duanpeng 目录下并用pwd查看当前的路径,请用上级目录名".."方式切换到 /liangjian/liyunlong下**
**[root@localhost abc]#** *cd /liangjian/liyunlong/weiheshang/duanpeng*
**[root@localhost duanpeng]#** *pwd/liangjian/liyunlong/weiheshang/duanpeng*
**[root@localhost duanpeng]#** *cd ..*
**[root@localhost weiheshang]#** *pwd/liangjian/liyunlong/weiheshang*
**[root@localhost weiheshang]#** *cd ..*
**[root@localhost liyunlong]#** *pwd/liangjian/liyunlong*
**5、请一次删除/abc下一次创建的1000个目录,请在/abc下用touch再创建20个以stu开头的普通可读文档,文档后缀为.txt**
**[root@localhost /]#** *rm -rf /abc/jhc{1..1000}*
**[root@localhost ~]#** *cd /*
**[root@localhost /]#** *cd /abc*
**[root@localhost abc]#** *touch stu.txt{1..20}*
**[root@localhost abc]#** *ls*
*stu.txt1 stu.txt12 stu.txt15 stu.txt18 stu.txt20 stu.txt5 stu.txt8stu.txt10 stu.txt13 stu.txt16 stu.txt19 stu.txt3 stu.txt6 stu.txt9stu.txt11 stu.txt14 stu.txt17 stu.txt2 stu.txt4 stu.txt7*
**6、请用cp命令将/boot/目录下以vmlinuz开头的文件拷贝到/abc下,并以查看他们占磁盘的空间大小。**
**[root@localhost /]#** *cp -pv /boot/vmlinuz* /abc*
**[root@localhost ~]#** *cd /abc*
**[root@localhost abc]#** *ls*
stu.txt1 stu.txt13 stu.txt17 stu.txt20 stu.txt6 *vmlinuz-0-rescue-6e2e1a50f0f14054bc3dbfef60ac5839* stu.txt10 stu.txt14 stu.txt18 stu.txt3 stu.txt7 *vmlinuz-3.10.0-229.el7.x86_64* stu.txt11 stu.txt15 stu.txt19 stu.txt4 stu.txt8stu.txt12 stu.txt16 stu.txt2 stu.txt5 stu.txt9
**[root@localhost abc]#** *du -sh vmlinuz*
*4.8M
vmlinuz-0-rescue-6e2e1a50f0f14054bc3dbfef60ac58394.8M
4.8M
vmlinuz-3.10.0-229.el7.x86_64**
**7、将其中一个vmlinuz开头的文件改名为kgc,另外一个剪切到/tmp目录下。**
**[root@localhost abc]#** *mv vmlinuz-0-rescue-6e2e1a50f0f14054bc3dbfef60ac5839 kgc*
**[root@localhost abc]#** *ls*
*kgc stu.txt11 stu.txt14 stu.txt17 stu.txt2 stu.txt4 stu.txt7 vmlinuz-3.10.0-229.el7.x86_64stu.txt1 stu.txt12 stu.txt15 stu.txt18 stu.txt20 stu.txt5 stu.txt8stu.txt10 stu.txt13 stu.txt16 stu.txt19 stu.txt3 stu.txt6 stu.txt9*
**[root@localhost abc]#** *mv vmlinuz-3.10.0-229.el7.x86_64 /tmp*
**[root@localhost abc]#** *ls*
*kgc stu.txt11 stu.txt14 stu.txt17 stu.txt2 stu.txt4 stu.txt7stu.txt1 stu.txt12 stu.txt15 stu.txt18 stu.txt20 stu.txt5 stu.txt8stu.txt10 stu.txt13 stu.txt16 stu.txt19 stu.txt3 stu.txt6 stu.txt9*
**[root@localhost /]#** *cd /tmp*
**[root@localhost tmp]#** *ls*
*hsperfdata_root
systemd-private-q2fIIW
vmlinuz-3.10.0-229.el7.x86_64ks-script-Sh71U1
systemd-private-rz9Cua vmware-rootssh-R7UdyCNlkt4X

yum.logsystemd-private-MfqphL
systemd-private-YRCaCn
yum_save_tx.2019-07-23.09-18.ddZD5c.yumtx*
**8、查看/tmp/目录下以vmlinuz开头文件的详细状态信息。**
**[root@localhost tmp]#** *stat /tmp/vmlinuz*
*文件:"/tmp/vmlinuz-3.10.0-229.el7.x86_64"

**9、用find命令查找/tmp目录下以vmlinuz开头及大小超过1M的文件**
**[root@localhost tmp]#** *find /tmp -size +1M*
*/tmp/yum_save_tx.2019-07-23.09-18.ddZD5c.yumtx
/tmp/vmlinuz-3.10.0-229.el7.x86_64*
