linux查看ip命令

linux查看ip命令：

Linux查看IP地址的命令--ifconfig

ifconfig命令用于查看和更改网络接口的地址和参数

$ifconfig -a

lo0: flags=849 mtu 8232

inet 127.0.0.1 netmask ff000000

hme0: flags=863 mtu 1500

inet 211.101.149.11 netmask ffffff00 broadcast 211.101.149.255

linux命令

是对Linux系统进行管理的命令。对于Linux系统来说，无论是中央处理器、内存、磁盘驱动器、键盘、鼠标，还是用户等都是文件，Linux系统管理的命令是它正常运行的核心，与之前的DOS命令类似。linux命令在系统中有两种类型：内置Shell命令和Linux命令。

1.修改/etc/profile文件,注释掉if语句即可

把下面的if语句注释掉：

# Path manipulation

if [ "$EUID" = "0" ]then

pathmunge /sbin

pathmunge /usr/sbin

pathmunge /usr/local/sbin

fi

修改为

# Path manipulation

# if [ "$EUID" = "0" ]then

pathmunge /sbin

pathmunge /usr/sbin

pathmunge /usr/local/sbin

#fi

2.可以使用ln 命令连接

下图是 *** 作详细过程

[Blinux@bogon ~]$ ifconfigbash: ifconfig: command not found

[Blinux@bogon ~]$ ln -s /sbin/ifconfig /bin/ifconfigln: 正在创建指向“/sbin/ifconfig”的符号链接“/bin/ifconfig”: 权限不够

[Blinux@bogon ~]$ su

口令：

[root@bogon Blinux]# ln -s /sbin/ifconfig /bin/ifconfig[root@bogon Blinux]# su Blinux[Blinux@bogon ~]$ ifconfigeth0 Link encap:Ethernet HWaddr 00:0C:29:D4:AD:D6

3.用su – root方法

[Blinux@bogon ~]$ ifconfig

bash: ifconfig: command not found

[Blinux@bogon ~]$ su - root

口令：

[root@bogon ~]# ifconfig

eth0 Link encap:Ethernet HWaddr 00:0C:29:D4:AD:D6

inet addr:192.168.13.132 Bcast:192.168.13.255 Mask:255.255.255.0

Linux下默认可以通过2个命令查看IP地址： ifconfig，在终端（Terminal）中，输入ifconfig后回车，可查看到IP地址 ip addr，在终端中，输入ip addr后回车，同样可看到IP地址。
