常用linux命令20个(常用linux命令的基本使用)

ifconfig命令

ifconfig用于配置内核常驻网络接口。它用于在启动时根据需要设置接口。

检查活动网络接口

[rumenz@local ~]$ ifconfig

禁用网卡

[rumenz@local ~]$ ifconfig eth0 down

启用网卡

[rumenz@local ~]$ ifconfig eth0 up

为网卡分配 IP 地址

指定 192.168.1.12 作为网卡 eth0 的 IP 地址。

[rumenz@local ~]$ ifconfig eth0 192.168.1.12

更改网卡eth0的子网掩码

[rumenz@local ~]$ ifconfig eth0 netmask 255.255.255.

更改网卡 eth0 的广播地址

[rumenz@local ~]$ ifconfig eth0 broadcast 192.168.1.255

45. uptime命令

uptime命令能够打印系统总共运行了多长时间和系统的平均负载

[rumenz@local ~]$ uptime

14:37:10 up  4:21,  2 users,  load average: 0.00, 0.00, 0.04

46. wall命令

管理员最重要的命令之一,wall向使用他们登录的每个人发送消息mesg权限设置为 yes。该消息可以作为参数给出wall,也可以发送到 wall 的标准输入。

[rumenz@local ~]$ wall "we will be going down for maintenance for one hour sharply at 03:30 pm"

Broadcast message from root@localhost.localdomain (pts/0) (Sat Jun 29 14:44:02 2013): 

we will be going down for maintenance for one hour sharply at 03:30 pm

47. mesg命令

让你控制人们是否可以使用 write 命令,通过屏幕向你发送文本。

mesg [n|y]
n - prevents the message from others popping up on the screen.
y – Allows messages to appear on your screen.

48. write命令

让你直接将文本发送到另一台 Linux 机器的屏幕,如果 mesg是y。

[rumenz@local ~]$ write ravisaive

49. talk命令

对write命令,talk命令可让你与登录用户交谈。

[rumenz@local ~]$ talk ravisaive

Note: 如果talk命令未安装,你可以随时apt或yum所需的包。

[rumenz@local ~]$ yum install talk
OR
[rumenz@local ~]$ apt-get install talk

50. w命令

什么命令w 看起来你很有趣吗?但实际上并非如此。这是一个命令,即使它只有一个字母长!命令 w 的组合uptime和who命令一个接一个地发出,按照这个顺序。

[rumenz@local ~]$ w

15:05:42 up  4:49,  3 users,  load average: 0.02, 0.01, 0.00 
USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU WHAT

51. rename命令

顾名思义,此命令重命名文件。rename 将通过替换文件名中的第一个匹配项来重命名指定的文件。

Give the file names a1, a2, a3, a4.....1213

只需键入命令。

rename a1 a0 a?
 rename a1 a0 a??

52. 命令:top

显示进程CPU.默认情况下,此命令会自动刷新并继续显示CPU除非给出中断指令,否则处理。

[rumenz@local ~]$ top

53. mkfs.ext4命令

此命令创建一个新的ext4指定设备上的文件系统,如果在此命令后跟随错误的设备,整个块将被擦除和格式化,因此建议不要运行此命令,除非并且直到你明白你在做什么。

Mkfs.ext4 /dev/sda1 (sda1 block will be formatted)
mkfs.ext4 /dev/sdb1 (sdb1 block will be formatted)

54. 命令:vi/emacs/nano

vi,emacs,nano是 Linux 中一些最常用的编辑器。它们通常用于编辑文本、配置、文件。

vi 编辑器

[rumenz@local ~]$ touch a.txt (creates a text file a.txt) 
[rumenz@local ~]$ vi a.txt (open a.txt with vi editor)

[按i 进入插入模式,否则你将无法输入任何内容]

echo "Hello"  (your text here for the file)
  1. alt+x(退出插入模式,记得在最后一个字母之间保留一些空格。
  2. ctrl+x命令或你的最后一句话将被删除)。
  3. :wq!(保存文件,用当前文本,记住!是覆盖)。

nano编辑器

[rumenz@local ~]$ nano a.txt (open a.txt file to be edited with nano)
edit, with the content, required

ctrl +x(关闭编辑器)。它将显示输出为:

Save modified buffer (ANSWERING "No" WILL DESTROY CHANGES) ?                    
 Y Yes 
 N No           ^C Cancel

点击 y 到 yes 并输入文件名,你就完成了。

55. 命令:rsync

Rsync复制文件并有一个-P切换进度条。所以如果你安装了 rsync,你可以使用一个简单的别名。

alias cp='rsync -aP'

现在尝试在终端中复制一个大文件并查看包含剩余项目的输出,类似于进度条。

此外,保持和维护备份是系统管理员需要执行的最重要和最无聊的工作之一。Rsync 是一个非常好的工具(存在,还有其他几个)用于在终端中创建和维护备份。

[rumenz@local ~]$ rsync -zvr IMG_5267\ copy\=33\ copy\=ok.jpg ~/Desktop/ 

sending incremental file list 
IMG_5267 copy=33 copy=ok.jpg 

sent 2883830 bytes  received 31 bytes  5767722.00 bytes/sec 
total size is 2882771  speedup is 1.00

Note:-z用于压缩,-v 用于详细,-r 用于递归。

56. free命令

跟踪内存和资源与管理员执行的任何其他任务一样重要,并且free命令来拯救这里。

57. mysqldump命令

你应该已经从该命令的名称中了解了该命令的实际含义。mysqldump命令将所有或特定的数据库数据转储(备份)到给定的文件中。例如,

[rumenz@local ~]$ mysqldump -u root -p --all-databases > /home/server/Desktop/backupfile.sql

Note:mysqldump需要运行 mysql 并正确密码进行授权。我们已经介绍了一些有用的 mysqldump使用 mysqldump命令进行数据库备份的命令

58. mkpasswd命令

制作指定长度的难以猜测的随机密码。

[rumenz@local ~]$ mkpasswd -l 10

zI4+Ybqfx9
[rumenz@local ~]$ mkpasswd -l 20 

w0Pr7aqKk&hmbmqdrlmk

Note:-l 10生成一个随机密码10字符而-l 20生成字符密码20,它可以设置为任何以获得所需的结果。此命令非常有用,通常以脚本语言实现以生成随机密码。你可能需要yum或aptexpect' 包来使用这个命令。

[root@rumenz ~]# yum install expect 
OR
[root@rumenz ~]# apt-get install expect

59. paste命令

使用行合并两个或多个文本文件

[rumenz@local ~] cat rumenz1.txt                  #rumenz1.txt文件的内容  
1
2
3
[rumenz@local ~] cat rumenz2.txt                  #rumenz2.txt   文件的内容  
4
[rumenz@local ~] cat rumenz3.txt                  #rumenz3.txt文件的内容  
5
6
[rumenz@local ~] paste rumenz1.txt rumenz2.txt  rumenz3.txt   
1
2
3
4
5
6

60. lsof命令

lsof代表 list open files 并显示你的系统当前打开的所有文件。找出哪些进程使用某个文件或显示单个进程的所有文件非常有用。

[rumenz@local ~]$ lsof 

COMMAND     PID   TID            USER   FD      TYPE     DEVICE SIZE/OFF       NODE NAME
init          1                  root  cwd       DIR        8,1     4096          2 /
init          1                  root  rtd       DIR        8,1     4096          2 /
init          1                  root  txt       REG        8,1   227432     395571 /sbin/init
...
