开发板没有ifconfig命令，怎么安装
ifconfing
-bash: ifconfing: command not found
[root@100ask:~]# echo $PATH
/bin:/sbin:/usr/bin:/usr/sbin
[root@100ask:~]# yum search ifconfig
-bash: yum: command not found
[root@100ask:~]# yum -y install net-tools.x86_64
-bash: yum: command not found
发现好多命令都没有安装
你再看看你写的命令呢
开发板上不支持yum
