[root@deploy network-scripts]# pwd

/etc/sysconfig/network-scripts

[root@deploy network-scripts]# ls

ifcfg-eth0  ifdown-bnep  ifdown-ipv6  ifdown-ppp     ifdown-tunnel  ifup-bnep  ifup-ipv6  ifup-plusb  ifup-routes  ifup-wireless     network-functions

ifcfg-lo    ifdown-eth   ifdown-isdn  ifdown-routes  ifup           ifup-eth   ifup-isdn  ifup-post   ifup-sit     init.ipv6-global  network-functions-ipv6

ifdown      ifdown-ippp  ifdown-post  ifdown-sit     ifup-aliases   ifup-ippp  ifup-plip  ifup-ppp    ifup-tunnel  net.hotplug

[root@deploy network-scripts]# cat ifcfg-eth0
