running ip addr:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
3: eth0@if10: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1460 qdisc noqueue state UP group default
link/ether 0a:58:0a:00:00:07 brd ff:ff:ff:ff:ff:ff link-netnsid 0
inet 10.0.0.7/24 scope global eth0
valid_lft forever preferred_lft forever
inet6 fe80::e837:feff:fe5c:c912/64 scope link

Is there some way that ip addr will return eth0 instead of eth0@if10 ? I saw ifconfig does list it as eth0 and not eth0@if10
If you just withs to get the entries left of the @, then use the following.
ip a | cut -sf1 -d@
You can add more filters before if you want to target specific interfaces.
