[root@localhost ~]# cd /etc/sysconfig/network-scripts/
[root@localhost network-scripts]# ls
ifcfg-enp0s3  ifdown-ppp       ifup-ib      ifup-Team
ifcfg-lo      ifdown-routes    ifup-ippp    ifup-TeamPort
ifdown        ifdown-sit       ifup-ipv6    ifup-tunnel
ifdown-bnep   ifdown-Team      ifup-isdn    ifup-wireless
ifdown-eth    ifdown-TeamPort  ifup-plip    init.ipv6-global

ifdown-isdn   ifup-bnep        ifup-routes
ifdown-post   ifup-eth         ifup-sit
[root@localhost network-scripts]# cat ifcfg-enp0s3
