Terminal- Bash question

[CTD12]

I need help on setting up the bash function in terminal. I am very new to terminal and never have taken courses using terminal or any kind of command prompt... just looked on the internet to find command lines i need. But what i need to know is how i can set up a text file to bash into with a command line that has multiple changes at the end of the command.
Example: i need to change my mac address at school so i can bypass the firewalls. I have five or six mac addresses that the schools firewall accepts but sometime one works and other don't so i would like to set up a text file that has the command: sudo ifconfig en1 ether with the 5-6 addresses in a list under to choose from. What i have to do right now is create 6 different txt files and bash into each one. Is their a way to put all 6 mac addresses together so that i only have to bash one txt file and choose which mac address i would like to connect to the command?
thanks for any feedback sorry if confusing,

MAC addresses are hardware identification, normally unique to a computer...

IP addresses sounds like what you are trying to change..

Big difference

Hi and the forum is not the place to ask to bypass restrictions at school. Thread closed.

Circumventing local school rules will not be supported here, sorry. I'm closing the thread and will move it out from Apple sub-forum to General Help.

Good to see we are on the same page overdrank :)
Merged the other closed thread in this one.
