シェルを使ってMacアドレスでデバイス名を取得する方法は？

Question

シェルを使って、MACアドレスでデバイス名を取得します。たとえば、Macは= "EC：F4：BB：E1：0C：1D"、および元の文字列が、このようなものです：

[root@yf-mos-test-net09 ~]# ip link show 
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 
2: eth2: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 
    link/ether ec:f4:bb:e1:0c:1c brd ff:ff:ff:ff:ff:ff

    link/ether 1a:e5:33:75:83:f2 brd ff:ff:ff:ff:ff:ff

    link/ether c2:15:a9:8b:db:40 brd ff:ff:ff:ff:ff:ff 
976: br_t: <BROADCAST,PROMISC> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 500 
    link/ether ec:f4:bb:e1:0c:18 brd ff:ff:ff:ff:ff:ff 
977: brpri: <BROADCAST,PROMISC,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN mode DEFAULT qlen 500 
    link/ether 82:f9:07:9d:d0:45 brd ff:ff:ff:ff:ff:ff 
978: breip: <BROADCAST,PROMISC,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN mode DEFAULT qlen 500 
    link/ether 0e:7b:96:6b:22:4c brd ff:ff:ff:ff:ff:ff 

私のpythonを使用している場合は、私は（re.splitを使用することができます）、私シェルで行う方法がわからない、CentOSの7で〜

ありがとう：get_device_by_hwaddr（）関数の

$ source /etc/sysconfig/network-scripts/network-functions && get_device_by_hwaddr 12:34:56:9d:5b:0a

出典：あなたがこれまでに試してみました何

$ grep get_device_by_hwaddr -A 3 /etc/sysconfig/network-scripts/network-functions 
get_device_by_hwaddr() 
{ 
    LANG=C ip -o link | awk -F ': ' -vIGNORECASE=1 '!/link\/ieee802\.11/ && /'"$1"'/ { print $2 }' 
}
