如题所述
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
下图是操作详细过程
[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

RX bytes:4570048 (4.3 MiB) TX bytes:4570048 (4.3 MiB)
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

pathmunge /sbin
pathmunge /usr/sbin
pathmunge /usr/local/sbin
#fi
