刚写的一个配置网卡的脚本

Yuri

刚写的一个Linux用的配置网卡的脚本，拿出来献丑，请各位多多指教。
超简单的一个东西，因为不会用循环所以只能这样，还有如何检测有几个网卡？

如何检测系统有几块网卡？

寂寞烈火

dmesg|grep -i eth

Yuri

各位大哥有指教一下撒!

dmesg|grep -i eth

不可以，结果不符合要求

lspci可以找到吗？

Yuri

可以看到网卡,但是我要得到有几个eth,是在shell中使用的,ifconfig -a可以看到所有,但是我不知道如何把eth0 eth1过滤出来.

晨想

ip link|grep "<"|sed -e "s/.: \(.*\):.*/\1/g"

Yuri

[root@Genv ~]# ip link|grep "<"|sed -e "s/.: \(.*\):.*/\1/g"
lo
eth0
sit0

wgmaster

这样不是更好??
dmesg |grep ^eth[0-9]*
