Hey guys, I want to use a a quick bash script/command to determine what network interface is connected to the internet so I can pipe it out to become a variable, in order so the user does not have to manually type it in each time or have to 'hardcode' the variable into the script.
I know about checking ifconfig etc of course, just looking for another way.
Many thanks and apologies for the kinda double post!
