variable with the MAC

Hi, i need a variable with the MAC. I’ve experience with bash but nothing with RouterOS. If i run:
interface print
i can see the MAC, but how i put it on a variable?

hello,

for example:

:local macaddress [/interface get ether1 mac-address]

i’m doing something wrong:
[admin@MikroTik] > :local macaddress [/interface get ether1 mac-address]
[admin@MikroTik] > :put $macaddress

[admin@MikroTik] >

:confused:

together:

:local macaddress [/interface get ether1 mac-address]; :put $macaddress
